22.5's on a SRW...

Evidently, the Michelin tire size 315/60 R22. 5 is sold only to the City of Las Vegas/Las Vegas Transit System for use on their subway cars.

Dang... I must be real old, I didn't even know Vegas had a subway.

Hey guy run them big twenty-two fives out to scottsdale and tell us how much your MPG changed I am really curious as to how much of a drop. trust me you wont mind the added attention.

It will be awhile before back in Scottsdale but I will keep all posted. I drove a 06 Duramax 2500 4X4 down there this trip and averaged 14. 5 at best (EMPTY) 3300 miles in all. NOT very impressed. I am however impressed with the ease of driving and very nice ride.



The 6 spd Allison is a very nice transmission with the tap shift... and hope to all that buy the new 68rfe will be as much transmission as the Allison.
