speedo correct?
Check out the stats on tirerack.com for tire dimensions. It lists tire diameters and other stuff. You can see if the larger width also increases the diameter. I doubt there is much of a diff in diameter between 235s and 265s. Best way to double check is run a measured mile at 60 mph (if you can bear to go that slooow). At 60mph, the mile will take exactly 1 minute. If it takes less, you speedo is reading low, if more than 1 minute, speedo is reading high. Hope this helps.....
