Replacing ST 235/80/16 with LT

Looking at Firestone Transforce HT. My rims are 16x6.0, can I use 245/75/16 or do I need to stick with 235/85/16? My axles are 33 inches apart, but with the the 31.7 inch diameter 235's, I don't think my x-Chocks will work.

  • I went with Firestone Transforce on my 16x6 rims. Replaced my ST235/85/R16 tires. Never had a problem.
  • I went with 245/75/16 Goodrich commercial ta's. width is not a problem on mine. rim width is fine, but you need to make sure you have the extra room on the inside of rim so tire won't rub against the trailer. there's very little difference in these 2 sizes
  • The 245/75's are smaller diameter but all specs say 6.5+ width rim. The 235/85 specs specify 6.0+. I guess I'll have to go with the 235/85.
  • When I switched to 235/85/16 B.F.Goodrich Commercial TAs my X Chocks worked fine. Then I switched to Michelin Ribs same size, and they won't fit now. The Ribs are about 1/2" closer together. Small price to pay for great tires.

  • That what I did
    but I went to a toyo HT tire LT 245/75/16 E
    will never go back to ST on my fifthwheel
