I just upgraded rim(alloys) + tyes of my REVO to 13 inch.
Tyre brand/model: NEXEN SB 702 (165/70/R13)
I tell you its huge improvement in the ride now.. WOW!!
So smooth and what a grip. simply amazing!!
I'd strongly recommend new REVO owners to get their car in 13 inch tyre. i think this car was made for 13 inch tyres as REVO 1000cc got 13 inch tyres as stock from factory.
Here is a shot from today right after Aftaar.

BTW Ramzan mubarak to all
