I need new tires and probably will get either Pirelli P-zero or Toyo Proxes 4, I have stock CL 17" wheels and not planning to upgrade. I was thinking that I can go 235 in width but not sure if it will create any kind of problems or mushy handling or something like that. Can anyone tell me if I should go 235 or 225?

235-45-17 is the correct size. You can go 225, however your speedo will be off a little. There are no problems with this size do a search on it, you will hear 99.9999% positive reports.

I've got 235/45 on stock wheels with no problems whatsoever and handling has increased a tad.

235/45-17 here as well...no problems and speedo is almost the same as stock.

but, will they fit with a drop...................1.5 in front and 1 in the back?

They look kinda funny though in 235/45

Wasn't there a rule of thumb, that if you increase the width by one step, you must decrease the sidewall by one step too?

Therefore the stock 215/50/17 should become 235/40/17 ???

That "rule of thumb" is FUBAR. Completely false.

I suppose it varies by manufacturer, but i put 225/45/17 kumho's on mine a few months ago, and they look perfect. I would not want them to be any wider, well i would, but not on the stock wheel.

I have toyo proxes 4s (235/45/17) on the stock rims with a comptech drop. No problems at all. The toyos do, however, have a "rim protector" bead that kinda sticks out and makes it look like the wheels are buried in the tire. Also, one tire guy said he couldn't align my wheels because they couldn't get the equipment mounted on the rim because of that.

Les Schwab said no big deal - just let the air out of the tire first, and the rim is plenty accessible.

But no rubbing or other problems, and the car handles 10 times better than the stock rubber.

03 CL TypeS

Can you go wider than 235's on the stock 17" rims / stock ride height ?

i.e. 255/40/17s or something like that?

Rock2534

that would probably look real bad, and might effect cornering, i would think.

Don't do it!

Technically we shouldn't even be running 245s on the stock wheel, but that's borderline. Going beyond this width on a 7.5" wheel is asking for trouble! Among other things, it doesn't allow the tire to attain its correct profile and work as it was designed.

235/45/17 Toyo Proxes 4's installed on stock rims today with a 4 wheel alignment.
Needed new tires as both fronts had 2 patches on each and 40K on the stock tires.

CL-S OEM wheels are only 17"x7" Technically you shouldn't go above 225

Rock2534

you don't have a 7.5" wheel, not a stock CL-S anyway. all tire manufacturers recommend a minimum 7.5" wheel for 235, i know many people have put them on their 7.0" wheels with no problems, i just don't find the appearance of it to be that good.

hemhaw

You're right, my bad... I knew that the CL wheels were .5" wider than the TL's, but I was screwed up on my numbers....

But he still should go no wider than 235!

Many shops won't mount a 235 on a 7" wide rim. FYI

aspar

ok, so despite what some people have gotten away with on stock 17" CL-S wheels... what is the maximum you sould really go on the tire?? 225/45?

Rock2534

aspar

thanks alot... im looking to replace all 4 on the stocks this week

I've seen 245/45/17 on stock CL-S wheels, didnt look that bad. I would stick with 235's tho, they look sportier & maintain correct diameter.

Thats Right, I have 225/45 Pirelli PZero Neros & I love them.

I would like to see how 'pinched' the 235s are though, any pics around?

I'm gonna be going with 235s this time around. It is nearly impossible to get 225s with the correct load rating for our cars. I've already blown 2 Pirelli PZero Neros in 225/45. I love the tire though. I might try it again in 235.

aspar

any pics of yours?

225/45/17 Pirelli PZero NERO M+S

I'll get some soon but the pics right above this is pretty much what mine look like...

i am thinking of going with 235/70/17 to smooth out the ride.

I really hope you are joking. They don't even make that size.

I just put on Toyo Proxes 4 and they're very good tires. Got the size 235/45/17. For some reason the guy who sold them to me said that P Zero's are not that great in handling compared to Proxes 4. Although a little more expensive. The car now feels more planted to the road (less body lean) and takes turns like crazy as well as high speed lane changes are more or less precise. Although I feel that it's still a bit sloppy because of stock suspension. I need an alignment also so we'll see how it drives after that.

235s look very nice, wide enough and nothing is sticking out. The pattern looks cooler than Pirelli also. I'll finally take some pics of my PDG CLS this weekend and then post them :o) My rims are not perfect though But they look good anyway, you have to look close to notice all the imperfections...
