HELP ON TIRE SIZE..., For 17's and 18's rims Options

[charming6gmoz]

I need help in getting the right fit of tires for the current rims I have.



A few days ago one of my front rims crack really bad in pieces going into a pot hole.

Right now my tires are 215/ 35 /18




I Want to increase the sidewall height to decrease the stiffness in my car
and wanted to know what is the highest height I can go
on the sidewall height for 18 inch rims and for 17 inch rims... ??????

The reason I want to know what is the highest I can go for 17's and 18's
is that the Company that make the rims I currently have doesn't make 18's anymore
and I have to place 17 inch rims in the front, but now I want to go the highest on the sidewall height..


Some people recommended me getting
215/ 50/ 17 for the front &
215/ 40/ 18 for the rear.

After i got my rims, the car became very stiff and
that is why I want to get bigger tires now so the impact
on the road won't feel as hard and the car can decrease the stiffness.

Is this the highest I can go on the tire size so none of the tires rub?
i would really appreciate your help..

If you go 18's, I think the ABSOLUTELY most is 40. I got 18's with 35 now, and they are almost rubbing when turning over at max. I think its place for a little more. But I dont think you will feel any difference from 35-40. If you want it more comfortable, you have to go down to 17's, with 50 or something. 18's are NOT comfortable on our cars without modifications.

What type of modifications do u think I need to do if I stay with 18's rims?
