For those who have run this tire, I am on stock suspension, -2.3 front camber with shims to get there, and I am getting rubbing when I have moderate compression on bumps that appears to be the front inner fender lip cutting into the outer wall of the tire (metal on rubber so it is gouging into the tire). I am using the 245/40/18 and this is just in street driving so far.

What size are other folks running? Do you think I need to go smaller with the 235/40/18? I am heading to the track next week and I would hate to have a tire failure because I slashed my own tire on a bump. Thanks in advance.

i have about 2.5 front camber
i used 245 and 255 toyo's only rub at full lock, not under compression.
so i dont know what is going on with your set up.

 

did you use shims or rotate the struts?

 

Shims.

 

try rotating your struts you start with 2.6 camber and it may solve your problem.

are you getting rubbing on both sides.? They might be uneven.

Lastly I rolled my fenders even more then stock that helps and is cheap. they are rolled only in the middle from the factory.

 

For a stock car (mine), the 245 sized fronts are too large. To keep things simple, I went back down to 235s and couldn't be any happier.

The same goes for the rear as well. 305s were just too tall and wide to avoid rubbing. Back to 295s.

 

When you "roll" the fenders, are you referring to the inside lip? For example, if I follow down the fender towards the wheel, just as the sheet metal folds into the wheelwell, it is shaped like a backwards L (vs. the center where it is more like a U). Is it the base of the L that you are bending in? Thanks. I actually tried a little of that yesterday but I am not sure I did enough. It does seem to be rubbing on both sides by the way.

 

Yup. Be careful of cracking the paint. That's the rookie mistake.

 

I get rubbing on PS2, Toyo and Hoosiers - its the plastic liner - had 3degrees, just changed to 2.5 degrees - still rubs.
Its also ride height connected - if its not the metal of the arch just make sure the brake lines arent rubbing and be prepared to replace the plastic arch liner at some point in the future.

 

A friend has had this happen with a Toyo 888 when he deviated over a high kerb and explored the gravel trap - but no deflation because it was in the thick part of the tyre wall where it curves into the tread area.

 

Well, I rolled the rest of the front part of the fender and it seems to be much better. I was very careful to keep the body panel hot with a hair dryer while slowly bending the lip. I didn't see any spidering or cracking of the paint. I think the tire still rubs the plastic liner occasionally but no metal on rubber. Is this safe on the track? Thanks for everyones advice. It appears it may have saved me $600 for replacing the brand new front tires.

 

what is your caster? 9deg will rub and you'll have the turning radius of a battleship

 

Caster at last alignment was 8.4 and 8.3.

 

I have 8.5 no rbbing. at 9 i did.

How low are you?

 

If you're below 100cm they will rub.
