Additional Rubbing?

Im currently running 19x8.5 et 35 on 255/35/19 squared pireli winters and im rubbing on full lock out and i was wondering if itll get worst if i lower the car on H&R Springs or coil overs? Was also looking to get the same size set for summers.

You shouldn't be rubbing with that tire size. Where in the wheel well are you rubbing?

That’s what Alohatoad told me. I’m rubbing on the inner fender on full lock.

I have noticed that winter/snow tire shoulders are often more square and tread width wider, which causes it to be broader/meatier than a non winter/snow counterpart in a given size.

I dont believe you'll have the rubbing issue with a 255/35/19 summer.

when you lower your car, slight neg camber is added which changes the orientation of the tire as it rotates about the kingpin axis, when turning the steering wheel. also the point of contact where the tire was rubbing (unlowered), also shifts higher on the liner.

I have noticed full lock rubbing is often eliminated from lowering. It would be interesting to see if lowering eliminates the rub with your winter/snow tires...

Also I don’t think I can add camber if I run springs 😅

on macpherson type fronts, with a lowering spring, the spring/damper assembly is shorter and the the angle of the kingpin axis changes slightly. the geometric change results in the slight negative camber being incurred.

Oh also what are your thoughts on rubbing 245/35/19 instead. 👀
