frind of mine is letting go of some 20in rims dirt cheap and they have tires on them already but not sure if the tirea will fit on my 99 gt the tires are 245/40/r20 but I belive the recomended size for my car is 245/30/r20 does anyone know if the larger side wall will cause any issues the car is not lowered

the issue most people run into when putting 20's on a new edge is something called mymustanglooksgayites it can be cured by getting an erection and running straight toward a brick wall

 

^yup...

 

Ditto

 

Unnecessary tone notwithstanding, I agree with the above sentiment also. 20s on our cars do not look good. But beyond that, if you like them, then the question is will the overall dimensions of wheel plus tire change? And based on the tires already on the rims, it will. This will at the very least throw your speedometer off. And they'll probably rub the wheel wells whenever you hit a bump as well. I had wider tires on a prior Mustang and they hit the edge of the wheel well constantly. You'd likely have the same problem, not sure how much 'spare' room there is in there...

 

Then, in addition to the silly look there is that a 20" wheel/tire combination will weigh more than a same overall diameter 17" wheel. This will hurt acceleration, and handling and ride quality on bumpy roadways will suffer as well...

 

Since when did physics, common sense and taste influence the majority of Mustang owners?

 

i always thought bigger wheels meant a more comfortable ride. just glide of those pot holes.

 

Are you sarcastic or ignorant?
