Spare Tire Size Difference

by Guest9370  |  earlier

0 LIKES UnLike


I drive a 4wd truck with 285-60-18 tires on it now. The spare is a 275-65-18. To my calculations the height difference is approximately 31.46 to 32.00 between the spare and the other tires. I am confused now, what to do and what not.

I want to run the spare on the non-drive axle without damage? In other words, can I drive it on the front with the truck in 2wd? Let me know if you have any useful information on spare tire size difference. Please help me in this regard.

    Yes it should work fine. But there are certain things to be kept in mind.

    Keep in your mind that a spare tire can only be used, driven on, from the time it is put on and driven right to a tire shop for repair replacement about a few miles drive time on a spare.
    You know modern cars come now from the factory with a space saver spare tire.

    However, I keep all tires, even the spare, and the same sizes. So just keep in mind there are some constraints while using a spare tire. You sound worried. If it bothers you, replace it. I hope your query has been answered now, still have something in your mind then do share with me. I am pleased to be of your help. Share anything which is related to spare tires.
