Curing mud tire uneven wear
Thought I would share this with y'all, as I know that everyone who runs aggressive treaded tires have run into this at one time or another.....
As you know, no matter how dilligent you are in rotating or maintaining tire pressure, tires with aggressive tread start wearing unevenly, causing roaring, vibration, and generally a shitty riding truck.
A friend of mine who is a third generation tire shop/towing guy, has a machine his grandfather invented back in the 50's. Back then, the steel wheels weren't 100% true and centered, and tire mold technology didn't produce tires that were completely round. His grandfather solved this by inventing a machine that that actually spun the tire on the vehicle and "trued", or shaved the high spots on the tire making it truly round. These machines rarely get used nowadays because tire and wheel technology has improved and everything is true and round.
Back when I sold tires several years ago, had a customer who ordered a new set of mud terrain tires for his truck. His old ones didn't have many miles, but were never rotated so they were severely cupped. I needed a set on a Rover I had, but couldn't afford any, so I put that used set on. Could barely drive it. I talked my friend into blowing the dust off the machine and truing the tires. From looking at the shavings on the ground it looked like most of the tire was shaved off, but the tread looked brand new, and the truck drove like it had brand new tires!
The 35" Kelly Safari TSR's I'm running now have about 15k on them, and were starting to roar. Talked him into shaving them, and now it's like I have a new set of tires!
These machines were marketed back in the 50's and 60's called the Amermac (Americus Machine Company) Tire Truer. If you can find an old school tire shop with one, you can save those old tires you were going to throw away!
