I am wondering what you guys think of the rear tires at 315/30r21 for the rear? I read an article about a track car (explorer st) that is set up for the track. Has roll cage and setup with 4 seats. They used a 315/30/21 for rear. Wondering if anyone has that size on their rear and if you can offer your expierence with them on the street. Also, wondering what widest set can go on the front without rubbing during turning. All this on H&R lowering springs. I am looking for a very aggressive stance. I like the low look with a little negative camber on wide wheels and large quad exhaust tips, 4" tips.

I ran 315’s square on 10.5” wheels.
You could run a 12” wheel out back if you did the math and got the offset right and fit a 325 back there pretty easily.

You ran 315/35r22 though without a problem right?

Yes. I wouldn’t recommend it if there was a fitment issue.
Some have ran an 11” wheel up front but they stick out too far for my liking so I wouldn’t recommend that. There’s just not enough strut clearance to work with. The rear is wide open for playing around.

What do you mean by fitment issue?

Currently running 22x10.5 square with 315/35-22 Conti DWS. Stock springs and no rubbing anywhere at all. She looks good with 4 fat tires on her.

Steeda springs on order, looks like everything should still clear when lowered about an inch.

@UNBROKEN 315/35/22 are about .3 in bigger in diameter than the 305/35/22 - and obviously wider as well.. i want to run a 315/35/22 in the rear and 305/35/22 upfront - i went with the +30 offset - will the 315 fit?

If your car is AWD there’s too much difference in OD between those 2. It’ll freak out the computer. You can run 315 square though.

Yep. There are quite a few running them (thanks to @UNBROKEN who did all the math to verify it would all fit) I've loved the look on mine.

You could run a 12” wheel out back if you did the math and got the offset right and fit a 325 back there pretty easily.
What offset were you running though? I found a pair of 20x10.5s I’m debating running with some 285/50r20s that have a +45 offset. Wanting to know if those will fit in the front and not come in contact with anything. If that won’t work I’ll just be going with a set of 20x9.5 +33.

(Also curious why you used past-tense, why get rid of the wheels you had? Or did you just get rid of your car.) (I previously had a set of 20x10s +25 with 295/45r20s and had to remove them because it made the steering WAY too heavy/difficult to what I can only imagine was because the offset was too low, even though they were perfectly flush with the fenders.) (I read somewhere that not increasing width inside oem specs and only increasing outside can cause that issue if you don’t have adjustable control arms and are able to reset the kingpin inclination angle.)

No you cannot run a 10.5 wide wheel at +45. +30 is the proper offset for that width.
