Looking to increase tire and wheel size to 275/35/18 on 2005 Mustang GT.. Anybody have any experience with up-sizing?

Have already installed new springs which lower the car 1 1/2".

275-45-18

 

285 / 35 x 19s rear
245/ 40 x19 front

No Problems

 

Can i see a pic of that SRQ05, why didnt u go with 255 in the front, is it becuase of the 19" rim?

 

I'll bite...

Front - 275/35-19 on 19x9 (35mm)
Rear - 295/35-19 on 19x10 (45mm)

ROH Drift R wheels and BFG KDW G-force tires

 

Nice looking wheels! Got close-ups?

 

275/ 40s on 18 inch Bullitts......

 

Would 275/35-18 be smaller in diameter than the stock 235/55-17? Someone told me they would be and would have the effect of getting steeper differential gears.

I want to upgrade to bigger wheels/tires, but I don't want them to be smaller in diameter than the stock wheels/tires.

Thanks for the help.

 

I'm thinking that 275/35-18's will have a smaller diameter making the wheel well gap more, even with the car lowered (stock diameter being 27.1" and these being 25.5"). They will definately need a speedometer correction (when you show 70mph, you will actually be doing about 65mph). I went with the 255/45-18's to keep these values close to stock.

 

Christopher,
These sizes in 18's will get you close to stock (27.18"):
235/50-18 @ 27.25"
255/45-18 @ 27.04"
265/45-18 @ 27.39"
285/40-18 @ 26.98"
295/40-18 @ 27.29"

I did a lot of research before I chose my tires.

 

f1-cobra, cool, thanks for that little chart, that is exactly what I was looking for.

That kinda sucks though. The only 275's in my price range are the ones that I mentioned...BFGoodrich GForce Sport 275/35-18 for only $159 each.

I think most other 275/??-18's are $200-$250...

Anyone have any moderately priced suggestions for 275's or 285's?

 

BFG KDW2's.... 285X30R20 Rear 255X35R20 Front.... LOVE them... no rubbing no complaints...Loads of Grip..
