Has anyone had a problem with this at all...I wanna do this with my 03 Cl with h&r springs and tokico shocks...what is the minimum width for a 235/45/17 tire, and what is the stock cl rims width....also does anyone on the forum know of any problems anyone has had doing this?

Lots of people have done it with no issues. Minimum width recommended by most manufacturers is 7.5". Mounting on a 7.0" rim gives additional protection to the rim. I personally like the look on the rim.

Yep, do it. It'll protect the edge of the rim better than stock and if the tire has decently firm sidewall it'll handle good.

If I got Toyo T1S in 235/45/17 on stockers, it should handle better than 215/50/17 Toyo T1S right?

I would say definitely yes. Any performance tire is going to make the stockers look like the piles of crap they really are. Those tires are wider and have a stiffer sidewall, thus they will handle better. They probably wont ride as good though.

Just depends if you want looks and wheel protection (which the stock wheels certainly sorely need), or you want optimum handling and tire performance. You need wider wheels for the tires to work optimumly -- preferably 8" width. Those tire/wheel width recommendations are not just empty headed drivel, they are for a good engineering reason...

Well said.

I have that set-up with the stock shocks and stock wheels, and I have had no problems

So with a 7" stock wheel you dont think 235/45/17 will help handling and traction at all? Also where does everyone get their stock wheels mounted on this tire since it is below the recommended minimum width.

Okay, so I want to keep the mileage and speedometer the same for the car, I also want to improve handling. My car is lowered with h&r sports drop and tokico hp blues shocks, I hear the 225/50/17 have a higher sidewall so I may rub. That throws that out. Then there is 235/45/17 and 215/50/17. If I have Toyo T1S for both sizes, and on my stock rims, will the 235/45/17 significantly handle better than the stock size, because if Im driving hard Im concerned about the safety of the 235/45/17...if the difference is minium I will go with Max performance tires in stock size. Thanks guys.

I ran 235-45-17's on stock rims for years. The T1's also.(2 sets) I had no problems at all. I had Tire kindom do it. It was around $800 for all 4 with the tire protection they offer.

As for the performance difference between the stock size & the 235-45-17 Toyo T1's I don't know. The stock size Toyo's will just kill your current tires & the stockers. As far as the upgraded size I'd say you will get a bigger contact patch(more tire will meet the road) which will help you get more power to the ground.

From what you say on how you drive, I'm not sure which would be better for you. Tire kindom does have a try it policy. You can try the 235's & if your not happy return them & get the stock size.

Have you ever had any problems with alignment or balancing of the tires as others have mentioned...because my drop is lower than yours, I wonder if they will have problems with alignment and so forth, i will have to call around to see who will put that tire on my wheel, I wonder if these guys even know that 7inches is to small for the tire

On the 2nd set I had I did have a balance problem once I rotated them after 5K miles. Tried 2 times & still had a 60mph shake. I was runnign 42psi at that time. I lowered them to 38 & had them rebalanced once more & that fixed it. No alignment problems. Don't think that was a tire fitment issue. Since the fist set I put 22k miles on them, the 2nd set 5K & then had the problem. These were on the same set of 02 rims that I transfered between 2 cars, the 02 I had & the 03 I now have.

42 psi is waaaay too high. Reccomended is 34psi for the stock tires, and 42psi is probably almost the max psi for most all season tires.
