Recaps on fire apparatus
Posted by Ralph from Wilton, CT, US on January 15, 2009
We currently use Goodyear only (state contract) new tires and my question is would it be beneficial to start running retreads on my drive axles We use 11 and 12R22.5 G164’s. I know the casing is important and also to have quality recappers, I think the price can be up to 1/3 savings. I know of one other fire department that uses recaps.
I think you have answered your question better than I can. If you have good casings and a good retreader, retreads can cost 1/3 as much as new tires. If you make the right choise of retread type, performance can be very close to new tire performance. Plus, retreading is recycling....good for the environment. Seems like a no brainer to me....go for it.
Trailer tire design
Posted by Erwin from NANJING, OT, CN on January 15, 2009
Why the trailer tire typically has a shallow tread design?
Trailer tires are the slowest wearing tires on a tractor trailer. They are free rolling and supply no steering forces as steer tires do. So, they wear very slowly and are likely to develop irregular wear if the intial tread depth is too deep. Trailer tires will actually wear longer and more evently with less tread depth so, this is a case where less is actually more.
