Time to replace the current tires on the MJ and wanted to know if I’d see a significant loss in power or potential axel/driveshaft issues. Current tires are Toyo Eclipse P205/70 R15 with stock steel 15x6 wheels. Wheel and tire weight 40 lbs. I have a stock set of alloy 15x7s that weigh 22 lbs each. I am considering the same size tires or 215/70 R15 on the alloy wheels. Depending on if I go all season or all terrain, and the size of the tire, estimated weight range is between 44 and 50 lbs. Any issues moving up to the bigger wheel, tire, and additional rotating mass? I know it’s very minor, one size up on both the wheel and tire, but once they’re purchased and on the truck, I’m stuck with them. Do you recommend staying at 40 or will I be fine at 45-50 lbs.?
I have the very desired 2.5L, 2WD, 4-speed manual with no power steering! Current setup is “peppy” for being the 2.5L. I drive the MJ about a dozen times a year. Given my location, you must use the interstates (65 mph) to get from point A to B. Thanks in advance.
