I was wondering i know last time i went to change tires i asked about going to 65-16 and i was told that could damage and caus ethings to go off and be harmful to the tranmission

what about if i change to a 225 from a 235
can i cause damage doing that
what could happen from that

thanks

For starters, what is the original tire size as shown on the driver's door sticker ? (and do you still have the original wheels on the car......)

original stick is 235 and that is the orinal size from the factory also they are the original wheels also
im not tryign to cheap out or anytihng i just wish it was not so hard to find 2 tires to match the ones i have a pair of 225-60-16 in the basment that came off of my old lincoln they only have 2k miles on them they cost me like 100 each and i can get another 2 for 89 each after shipping
other wise im going to spend like 450 or 500 on 4 new tires again
only tires i like are michalen symmetrys or kumo solus
only tires i really trust for some reason
so just trying to see if the 225 will be ok or if not also

why what could happen from it

thank you

Looks like the 225's are about 1/2" less in diameter that the 235's, so you'll lose 1/4" of height - not enough to worry about. Your speedometer will read a tad high: when it says 60 you'll really be doing about 58.5.

Otherwise, it's just a slightly smaller tire, so you'll have no problems.

also will i be throwing anyting like the MPG off will i loose and go down to a lower MPG or is that not going to happen
and also with the tire being smaller i know like if i fill my tires with 45 psi air
it makes the ride stiffer then if i put 35 and 40
will the lower tire my make ride stiffer ?
or will it just make it more responsive

thanks

You'll probably never notice a gas mileage change. No need to carry high psi - run them at 32 psi, cold, and don't bleed any air if you check them hot: the pressure will be a bit higher, hot, and that is normal and built into the tire specs. I also doubt that you'll notice any ride change, BUT you are going to be running a slightly smaller tire load-wise, so treadwear may be somewhat more than predicted by the UHTQ rating.

I've got 225's on my STS and they have been fine. You can physically tell the tire is a bit smaller, but it's not too bad. The ride quality is pretty damn good (we're talking cheap Tiger Paw Uniroyal's here), but with the smaller size the handling takes a hit. Took my car (which had 235 Michelin Symmetry's before) from a good handling sedan to a true marshmellow - were talking Deville here.

If you're aren't worried about handling I'll say go for the 225's. If you still enjoy taking your car around bends - spend the extra $$$ for the 235's.

Yeah, that.....He's trying to use up a spare pair of 225's in the basement.......

I guess handling really isn't as much as an issue here as cost is. I'm going back to 235's next time. Symmetry is a good tire, but I want something a little more sporty. The Pilot MXV4 is looking good right about now, but a little pricey.

Go to www.coopertire.com and get to their CS4-V all-season H-tire. I've been running them for 2 years now and am pleased. Great in the rain. They have a long treadwear life and come with a "Try 'em for 45 days. If you don't like 'em, we'll take 'em back."

My 2002 SLS came standard with 225/60/16s. So go for it. You will have no issues
