i installed the 22 inc in my car yesterday. the wheel is 255/30/22
when i turn the car hard i hear a little bit rubbing. how can i fix it ? do i need to cut something ?

 

[still_walkin]

first off man it looks clean however if its a daily driver and its is take them off. the reason being is that if the rims are bigger than 8.5 on the width when you turn they are going to rub . the car is designed to turn a certain size tire and going bigger throws everything off. for instance the braking the rotors all going to go out and the leveling system its going to have problems when you have a car filled with people and a full take as for the tranni my friend had a 02 seville 22s same size tire and his tranni went out out twice in a 6 month period. its just too much on the cars suspension and costly i would throw some vogue rims on it and some vogue tires and call it a day. the older generation is going to hammer you on this but im not too older than you 28 and seeing this and trying this i was a victim of a tranni going bad due to rims ... but if you do insist you cantake the inner wheel well out and try spacers or a smaller tire. good luck

:yeah:

i like stock, but anything more than 20" is asking for a lot of trouble on the FWD Northstar K-Bodies

you can make it work with spacers and other 'tricks' but the physics of the chassis/brakes/steering/suspension are all thrown off by too much when you go that big and you end up with problems like this

other potential problems were mentioned above... add to that the possibility of excessive tread wear (especially on the fronts) ...

i don't care about the suspenstion. Strut or Shock. i just replace it and it still in Warranty. or Brake rotor or pad is cheap.
i use this car for daily drive. but this wheel will kill the transmission ? why ? because it is not too heavy and if the car carry it...it look like carry more 1 kid.
i put the original stock rim and this rim in the scale. this wheel and tire just 10 kg heavier than the stock. i mean 4 wheel.
and when i go 65 mph(the cluster said) the original speeds 68 MPH.

The transmission was designed to turn a certain tire size and anything more than plus two is asking for trouble. Putting The transmission to turn bigger rims than usual is making it work harder plus worsing off your gas milage. On the strut issue to replace a strut on just the rear is going to range 400-600 .also it will void a warranty by the Caddy dealership if they see those rims or the wear and tear is noticeable from that.another thing if your air strut strikes a leak and your car rear end drops you cant drive it to the shop verses if you had a stock or slightly larger you would be able to drive it in. Check other forums on larger rims

dont go bigger then 20s i drove 2 summers about 45-50k miles on 20s in 2 sumemrs and not one problem was caused by the rims
22s i had for about 2 weeks and they where terible

better be carfull and read your warranty info
and also find out about things
cause when you change stuff from it's original specs sometimes that will void your warranty

When i was looking at a 09 Charger Last year in April before deciding to get the HG's done on the caddy
the dealer said that if i put my 20s on that charger it will void out some warranty like drive train and other things cause they are not original specs
that also went for steering and suspension stuff

i so agree and ironically i was talking to a friend of mine and he shared a story when he had 22s on his 02 seville he hit one of those metal sheets they put in the roads to cover a hole in the road and behind it was a pot hole. and we all know what happened next. his to front tires had the air knocked out and he cracked one rim.... he had the same tire size you have. discount tire recommends no bigger than 20s but hey i would personally go no bigger than 18 since your factory size is 16. as a owner of two caddys total and being around them learning how they word FWD caddies and rims don't mix . its like oil and coolant. if you want 22s on a lac get a 70s model thats RWD or a another RWD caddy. the reason is your drive train in the front (transverse motor) and you turn in the front verses the drive train in the back. but im say its clean i envy you cause i wouldn't do that to a deville again. i miss my 100 spokes but with the suspension parts and brakes going out twice as fast my pockets say no.

What about the newer 2006-2011 models? I'm interested about this because I was contemplating whether I should put 20's or 22's on my 2011 DTS.

 

[still_walkin]

i believe the 06-11 models are fwd so no i wouldn't go bigger than 17" but if you don't want to take our advice keep the rims on the car and let time take its course. its not we are your mechanic telling you this we are giving u advice for free so there is no gain on our part. so if the car is a daily driver take them off. if its a sundays car or every once in a while u might be ok. caddy are hi manint as it is if you use them as a daily driver but to add more strain to your drive train is a receipe for disaister

 

[ogbuehi]

OP, the easiest way to deal with your situation is to get thinner tires. Your tires are 10 inches wide. You probably need to go with a 9" wide rim. That's most likely the easiest way to keep 22" rims on the vehicle without rubbing.

 

[weister42]

Here's a Deville DHS running on 28 inch rims

If I remember correctly... to make 22s work you need to get a 2 inch lift on all 4 corners and you MAYBE have to trim the wheel well. As far as performance/braking/mechanical issues I suppose if someone wants big rims they're gonna want to drive slow so everyone can see the bling yeah?

 

[still_walkin]

its not driving slow so everyone can see. its incase you hit a pothole or bump in the road you wont have the space between the car and frame for the wheel to move freely in the wheel well good luck trying to react to an un expected pothole in them 28s. u want big wheels get a suvs its a cadillac not a tractor

 

[ogbuehi]

Those 28" rims look nice. You can see there's no rub probably because those are only 8" wide rims. Just go with a thinner rim and you should be good.

 

[cadillac kevin]

you need to downsize the rims by at least 2 inches and make them narrower by 2 inches. the first is so you dont cause trans or engine failures (seen it happen many times). the second is obvious clearance issues.
as for the 28's- those rims look like they're 10 inches wide- but they have wheel spacers behind them (notice how the rim sticks out past the body). IMO that deville looks like a ghetto micro machine.

 

[ogbuehi]

I think he would need spacers because the rims have more of a RWD offset. But if he has spacers then that explains why the rims are barely sticking out. I've had a 9" rim with a FWD offset that fit just fine on a older caddy with a smaller wheel well.

 

[SPreston2001]

22's on these cars can be done with no problems what so ever. You either have a rim that is wider than 8.5" or the incorrect offset on your rims. If I can remember the offset should be anywhere between +30 thru +40 on these cars. I also noticed your tires are 255's and you should have 245's. Thats the tread width and if your tread width is too wide that will cause rubbing. I have 20's on my STS and had 22's on it before I sold them this spring and never had any problems. Matter of fact I have NEVER had any issues whatsoever with putting rims on any car I have owned. As long as you stay within the right specs (offset, bolt pattern, width, tire size etc) the only thing that should slightly change is your ride quality. Yes your going to lose some of that Cadillac ride but if installed correctly with some decent tires, it shouldnt be much worse. Installing 22's on these cars doesnt require any lift kits or anything, they should tuck right under the car with no problems. People just make the mistake of thinking ANY 22" rim thats 5x115mm will work.

I also noticed your tires are 255's and you should have 245's. Thats the tread width and if your tread width is too wide that will cause rubbing./QUOTE]

Ummmm.................No. Those numbers - 235, 245, 255 - are tire section width. Treadwidth is an entirely different figure, and is only found in the individual tire specs in www.tirerack.com

If the new tire outside diameter is greater than OEM then rubbing, transmission, and speedo errors come into play - those OD figures also come from each tire's spec sheet.

 

[SPreston2001]

Sorry Sub thats what I meant when I said tread width. When I had 22's on my STS I could turn my wheel as tight as can be without any rubbing. I sold them because I never really fell in love with the style of the rim but I got them for a steal so I couldnt pass them up. I sold them for more than I paid for them and thats when I brought the 20's that are on there now. I know plenty of people with 22" rims on these FWD Devilles/Sevilles and have absolutely no rubbing issues. My 22's still had the little stems on the tires when I sold them.

 

[Submariner409]

Yep - My analogy is that, if you keep the same outside diameter as stock (in order to keep the proper speedo, powertrain, and shift controls), you could then run "27's" (just wheels, no tires) with no rubbing - but the ride would be a bit weird.

If the car originally had 16's, then the 27" OD figure would give 5.5" of air and rubber between the wheel and ground. 17's, then 5" of cushion. 22's, then only 2.5" of cushion - and a harsh ride for the suspension to try and control. 24's or larger and the necessary tire diameter increases make the car look like some sort of Florida swamp buggy.
