Sorry, but you have to know that that much difference in tire size between the 2 axles, plus that 1 tire at double the tread height of the rest is gonna throw your axle ratio/tire rotation out of sync. Your axles are constantly fighting each other. Get your tire height matched between the 2 axles and hope you didn't burn up your differentials to much.

Thanks Chamber, Rawze.

I was thinking that I was still very broke after my inframe and couldn't actually afford ANY tires, but knew I had to do something before I had more tire failures. The remaining 4 will be replaced very shortly and that one oddball new tire will become a spare. Honestly, didn't think the difference between the axles would be that significant. I was more concerned with matching up tires on the same axle. At the time 4 tires was the absolute max I could manage (aka .

Probably be another 2-3 weeks (although I'll call now and see if I can get approval through our national account sooner) before I can replace the remaining 4.

Is there a better way to remount the existing tires until I can finish replacing them?

Also, any opinions on the u-joints? Meritor vs Spicer? Spicer's seem to run about $50-100 cheaper. They are a well known name, but I don't have any first hand experience with them to help make a decision between the 2. Did I get the part numbers right? Dealer just said CP25 for the front and CP20 for the rear.
