265 to 285 tire

[jeepit]

Currently have stock 265 stock size tires. Want to move to 285's. Need to know from anyone out there that has a 6 speed with 3:55's what RPM you are at in 5th gear at 65-70MPH.

285 is the width not height so no way to answer that question but there are many online calculators that would show you rpm for different tire sizes once you have all the info.

If it is a 32" tire I come up with 2422 rpm @ 65 and 2609 rpm @ 70.
