Please Help!!! Question on new tires.

TXSpeedDemon · 11-14-2013, 11:34 AM

a 245/40 will give you a diameter of 26.7" - only 4mm difference from your rears at 27.9" and closer than a 275/35. A 275 won't have any stretch and will definitely rub the front tabs on any dips/bumps.

245/40 and 285/35 is what I run and it has minimal rub only on big dips. and I'm a bit lower than you too.

Thank you everyone for the response. I'm going to try and switch out the front tires and see if that fixes the problem. I'm hearing 275/35 and 245/40. Does anyone have suggestions/experience with this sizing? I appreciate all the help.

Lol that's the OEM sport size.

Who in the hell had those other sizes on there?! The fronts were just plan stupid. Closer to square the better.

Damn how low are you? Whats your camber? More negative will help in more than 1 way.

Dropped on H&R Springs - about 1.3-1.5"s. I don't remember the front camber off hand, a little under -2 and within factory specs up front. Rears were like -2.1. I only rub the little tab sections inside the front wheel well - the part that sticks in toward the tire more than the rest of the liner. I don't hit the fender at all. And this only happens on really large dips when driving at speed.

If the tires really are the problem then the 245/40 will fix it without changing your rears. I'm running 245/40 and 285/35 without issues - other than the slight rubbing described above.
