Thread: 235/85R16 vs 255/85R16

I once saw a 235/40 fitted to a 254mm rim.....the owner said they handle better this way something tells me he was probably running 20 degrees of camber

Everyone else's 255/85 fitting charts use 6.5-7.5" rims with 7" being the measuring rim. I ran two sets of BFG's in that size before the 762's.

I think I mentioned it to my tyre bloke who told TyreMax but they were too dumb to do anything in their new catalogues.

That sounds about right, have gotten mud in the bead causing a slow leak as well. I'm tempted to put them on my 6.5s but I only have 5 rims for 6 tyres. Also the 6.5s are tube type (never caused me any problems before till I actually used them with tubes).

Hahaha, what's a tube ?

Dare I or anyone ever mention again running tubeless on a rim without the safety bead.....

I ran 255 85 on 16x8 with out a problem. Did lots of off road road some times aired to 12-15 psi with out a problem.

I agree 7 would be better how ever I wanted the track increase from -25 offset which is not avaible in 7s unless you mod disco rims.

Tire Rack just advised they can no longer ship BF Goodrich to Australia!

Thats a bugger.
Will have to buy 255/85's well in advance of needing them now I guess, or risk the usual "no stock and we cant tell you exactly when they'll be available" from local suppliers.

Tube? What Tube? Did the cape/Gulf trip twice in the 11A SWB Softtop in the '90s with 7.50 16 BFG AT's on the standard rims and not not a tube in sight!!
Never 1 bit of problem . not even a flat in the whole trip of 5000+ MILES!!!

Haven't run them for 8 years or so on non safety beaded rims

Plenty of us do it without issue, but you'll always get someone screaming we're all potential killers and our tyres will roll off the rim when we have a puncture.
Which funnily enough happens when you have a sudden deflation with a tube.

Rolled a tyre and tube off the rim @ 100km/h once on a corner. Luckily it was the unloaded front tyre tyre.
When i went to get it repaired my old tyre service bloke asked why on earth I was running tubes anyway, the bead is that bloody wide on the 6.5" rim and I'd been welding tubes to tyres and it was all just silly, so haven't run any since.
