Bruce Posted June 26, 2013 Share Posted June 26, 2013 Hi guys, My R50 is using 265/75/16LT 10PR and looking for new sets. There are 6PR 8PR 10PR tires but not sure what's different on road. Does it affect traction? It seems more PR = more weights so I guess it affects MPG. Should I insist 10PR? Thanks, Bruce Link to comment Share on other sites More sharing options...
Trogdor636 Posted June 26, 2013 Share Posted June 26, 2013 You'll be fine with 6. You'll probably find your ride to be less harsh after you switch to 6. Link to comment Share on other sites More sharing options...
Kingman Posted June 26, 2013 Share Posted June 26, 2013 10 ply is a stout tire and really unnecessary unless you're hauling some serious weight constantly and driving over sharp rocks and small bombs. Link to comment Share on other sites More sharing options...
Bruce Posted October 13, 2014 Author Share Posted October 13, 2014 (edited) Hi All, I changed my generator 2 days ago and the technian told 6PR should run at least 40psi and 10PR needs 50psi, in order to protect the steel layout. The other result form Google is 80% of the max cold pressure. For instance, my AT has max load with 80psi cold, so it's better to put 64psi. Any commets?

Karmann Posted October 14, 2014 Share Posted October 14, 2014 6 ply should be fine, i run about 35 psi in mine and have a really comfortable ride. No need for 10 unless you're going on sharp rocks a lot, or drive a 3/4 ton truck. Link to comment Share on other sites More sharing options...
