I am planning on buying the Toyo Proxes S/T 255/60/18, next week. I spoke with a representative with Nissan and he said that it will affect my speedometer about 10 mph going 65 and could mess up the computer. Any truth to this?
Thanks for you input
The representative from Nissan doesn't have a clue about tire sizing. As long as the diameter of the tire is unchanged, the speedometer will not change either. 255/60/18 has an identical diamter to the stock 235/65/18.
As a general rule of thumb, you want to stay within +/- 5% of the original tire diamter if you go with a non stock size.
TBogie: I concur with others concerning diameter. Negligable difference, but the ride is much better and handling is really nice in the sweepers, etc. And looks are nicer, beefier. A really nice upgrade.
We have 25K on ours and they are still fine. Darrell.
