    235/65r16's ?

    Has anyone ever tried to run 235/65r16's on a first Gen CTS? I came across a great deal, 4 almost new Blizzak's for $75! Great deal if they will fit!

    They will fit. Those are only a bit bigger than the stock tires. Lots of room in them wheel wells!

    Found an interesting size chart, 25.7 vs 28 inches in diameter.
    8.86 vs 9.25 inches in width. The best part is it calculated how much your speedo would be off! Most sites don't like link postings, so I didn't post it.

    That's pretty neat. The guys here post links all the time so if you want to share it with us or not, no one will give you any problems. In fact you may be even helping someone out who is wondering about tire sizes as well.

    Gladly! The best part is it also shows you the speedo conversions. I hope it does help someone else....

    Maybe tire sizing works differently on whatever planet Blayne is on, but here on Earth a tire that's over 2" bigger than stock is a massive difference.

    That's an SUV/minivan tire. If you're cool having a car looks like it's been lifted, is slower due to the large effective final drive ratio change, has a speedometer and odometer that are 8+% off what they're supposed to read, and probably rubs the front of the fender wheels when you turn the wheel, go for it!

    Ok, first things first, AAIIIC, you have come across lately to me to be a pretty big *******. You never have any normal comments. You are always on here trashing everyone else's comments. There are ways to reply to a post without being a douche bag.

    Secondly, yes the tire is 2" bigger. He has a 16" rim. You can put 22's on a car and you are saying that a slightly bigger tire won't fit with stock suspension. The tire is 2" larger, so it is actually going to be an inch further into the wheel well. To the OP, look at your car right now. You probably have a out 2-3" minimum of wheel well gap. I would bet quite a bit that those tires will fit just fine.

    Thanks Blayne....I thought it was just me! It was a rather strong response.....lol. Well I bought them, I guess they will either fit or I will CL them closer to winter (or maybe I can use my slow, lifted CTS for better ground clearance, lol!!)

    Sorry if I got sand in your mangina. If it makes you feel any better, I don't really think you're on another planet.

    (1) The wheel diameter has nothing to do with tire diameter, so I'm not sure I understand what point you're trying to make. Of course one can fit 22" wheels on the car, assuming you fit tires with appropriately shorter sidewalls. It's a very simple concept, and has nothing to do with the question posed in this thread.
    (2) A 2" change in tire diameter is not "slightly bigger". When it comes to tire sizing, that's a huge difference.

    The top of the wheel well is not the limiting factor in tire fitment.

    Good luck! It should certainly look interesting.

    Coincedently I purchased some 17" chrome oem's from a guy who had them on his Escalade. 65r/17's tires and rims for $200 he wwas moving.
    (For my 06 3.6)
    They fit in the back really snug..too big to turn the front wheels. I'm just going to go 50r/17 for the front until i can get a whole set for Winter.

    What was the offset on the escalade rims? Might have been the problem.

    And what size were the tires? "65r/17" doesn't mean much of anything - it's only 2/3 of the equation. I'm guessing since they came off an Escalade they were something huge.

    Yea like Blayne and AAIIIC both stated there are lots of factors that determine why they wouldn't clear the wheel well or why they rub when you turn the wheel. The width of the tire could have been the reason for the front tires rubbing.
