305/30/19 tires

No rubbing on the stock wheels for a 305 tire. Tire fits perfect in the car, but the stock wheels are just 10" wide. The 305 is a little too much for a 10" wheel. An 11" wheel would be better for a 305.

In regards to the 305/30 having a lower profile, there is no problem with the electronics (e-diff, ct, cst, etc). I'm running a 295/30 R888 instead of the 285/35 stock size, and despite being shorter, everything works well. Indeed, the shorter 295 gives me shorter gearing, bad for fuel economy, good for performance.

 

Im running this size on my stock scud rim and the rim is no way over tyred and fits nice. Much better rear grip and looks good too. Cheers DM

 

I know this is an old post... but can anyone here post some pics of a Scud with 305/30/19 mounted on stock wheels? If I put 305s on the rear, the front tires will be 245/35/19 or 255/35/19? Thinking of getting Trofeo R 305/30/19 245/35/19 with 5 or 10mm spacers... Thanks!

 

DH- Both Pirelli and Michelin recommend a minimum wheel width of 10.5" (10.5"-11.5") for 305/30 19s. Scud/16M rears are 10". Might make the wheel/tire unit insufficiently stiff on too narrow wheels, especially with the cornering and braking forces a Scud can generate on DOT legal competition tires. How about 295/35 19s for a compromise?

 

yeah I know about the rim width of the scud, but
I prefer on using the trofeo r, since they don't make them
on 295/35... only MPSS so thats why I chose 305/30, I think someone
already used 305/30 on stock wheels. The 295/30 might be small in diameter
since its .8" undersize than the stock tires.
