Default 275/30/19 & 305/30/19 am i gonna be okay?

Hey guys..this is my current set up...


245/35/19 & 275/30/19


Tomorrow I am picking up a pair of 305/30/19..my question is ...if i put the 275 in the front and the 305 in the back will I be okay?

I am riding on stock height right now...any rubbing issues?

Or should I leave the 245's in the front ..and just change the rears..reasons to change the rears is try to kill the rear gap and also the car keeps slipping as the rear tires are the wrong size.

Car has it sits now.

Actual speed 100.0 MPH. Speedometer will read 101.82 MPH. This is acceptable.

Rear tire circumference is 2.8 percent MORE than front tire circumference. VDC will be happy.

I think the rear will fill the gap a little better.

Please post pics of the setup when you have yjr 305s on. This is something that I would really consider when I get 10.5" rears. Thanks.

Tires are good sizes - I liked running them exactly like that. Equally as important, however, is the wheel width and offset. Do you know what they are?

I ended up getting 295/30/19 Pirellis P-Zeros..will post pics when I mount them...

Also the tire shop guy was adamant about not letting me put the 275's in the front..he said your car was made for 245's in the front

Tire shop is wrong - 275/30 is great in the front. Tell 'em I run 305 in the front, and they can stick it!

Your tire shop guy is an idiot and know nothing about this car. You can even tell him that.

The 275's were fine, you just needed a drop.

i would have went 255/35/19 and 285/35/19

but if you are going 275/30/19 and 295/30/19 these are nice sizes too just may need a mild drop to make it fit snug

305s would definitely warrant a fender roll and a "more than usual" negative camber. What offsets are your wheels?

Not really, with the proper offset just a mild roll will be needed and camber can be kept in the factory spec range

You can't say the first part without knowing the second part. 305s easily fit on the right sized wheel at the correct offset.

(Even no roll with a high offset wheel.)
