Hello,

I would like to know if someone has tested this diameter or knows if it would fit in the rear? Not the width but the diameter.

I'm hitting 130mph at 6800 rpm or so, I would like to drop it to 6500 or closer.

Wheel is 11" width and 18".

Thanks

Too many to list
OEM diameter is 26.6". I think +1" will be fine as long as it clears the fenders.

I run 305/30 20" and diameter is 27.2" - cutting it close on H&R suspension... but haven't had any problems. the Velgens are lightweight.

Cool story. What does that have to do with the OP's question about 305/40/19?
Actually 305/40/18

I think it should be ok right? Is about 0.8 inch larger than stock, is almost the same as using springs to lower 1" on stock diameter.
