Hey guys, so I have the Grand Touring wheels 245/40/18 fronts and 265/35/19 rears.

Would it be safe to get 305/30/19 for the rears?

 

What is minimum width for a 305, and how wide is your wheel?

 

it will buldge a bit on a 10 inch wheel but it will work.

 

It works fine if your not lowered.

 

I would go 285/35

 

its safe....but it wont look as good...on a 10 inch rear...i say max 295....i put some 295/30's on a ten inch wheel today and it was perfect

 

What size is the wheel?

 

Do you mean on the factory/OEM grand touring wheels? or aftermarket wheels?

 

I believe he has 19x9 front and 19x10 rear (Grand Touring wheels). I have 285/35 tire on 19x10 wheel, and the tire is flush with the rim.
So 305 should be no problem considering the +30mm offset, you shouldn't have any issues with the tires rubbing. Like mentioned above, the tires will bulge out a little.

305mm = 12 inches.

 

I'm also 285 on a 19x10 and as you mentioned, the tire is flush with the wheel lip. I'm sure that I could safely run 305 on mine as well.

 

Never mind. I thought this was important. Important enough to say “thanks” or simply reply.
