TIRE TIRES TIRES

It's about time. I was wondering if we were going to have a tire thread this week. Holding my breath and waiting for the next GVWR/GCWR thread.

I went with the LT245/75/R16 XPS Ribs to replace my old ST 235/80R16's. Nearly the same height and about 1/4" wider. Had more room in width than height.

1. Tire growth due to centrifugal force at high speeds, although the steel radial construction should be more stable.

2. Suspension droop (downward movement) since the shackles are at the outer ends of the springs, right? The inner ends of the spring are fixed at the equalizer, so as the springs shorten under droop, the axles will tend to move closer to each other.

I'm not saying the tires WILL touch - just that you have less than the 1"-2" clearance between the tires that is normally desirable.

No chance of swapping since I had Discount Tire special order them for me. I really didn't even think about the clearance since it's the tire size HitchHiker says to use.
Are there any scenarios where the tires could get closer together and rub??

That's pretty tight. It's too bad you've already bought the LT235/85R16 tires as there's also a LT245/75R16 Michelin XPS Rib that has the same load rating but is about 1.6" shorter in diameter (32.2" versus 30.6"), according to the spec sheet. Any chance of swapping them???

After reading all the post's I went with the Michelin XPS rib LT235/85R16 on my 2006 HitchHiker II, which I recently purchased. The manufacturers tire size tag says to use the LT not the ST like the trailer had on it when I bought it. My concern now is that with the LT235/85R16 is quite a bit larger in diameter than the ST235/80R16. Consequently I now only have 1/2 inch clearance between the tires! Is this enough clearance?
Thanks

Show us the LT tires on your trailer are anything you'd mount on a truck.

I ran LT235/85R16E Michelin XPS Ribs on both my 2002 Ram 3500 dually and my 2000 Jayco Designer XL 3610RLTS quite successfully. This is an all-steel construction all position tire that's widely used as both a truck and trailer tire by oil field hot-shotters because of its toughness, durability and long tread life.

Yes, that is a great tire, but not common in the snow belt, thus not often recommended in most areas of the US.

There's always the Michelin XPS Traction variant with the same carcass construction and a more aggressive tread pattern.

You were lucky to find a size match for truck and trailer. Today's truck tire sizes make it practically impossible and sizes that do fit common trailer sizes wont be found in common truck tire sizes. There are very few exceptions.

In my current case, the trailer runs Goodyear G114 tires in a 215/75R17.5H size designation (no P, LT or ST designation whatsoever) while the truck runs an LT235/80R17 tire, so especially with heavier trailers, there's not much chance for commonality between truck and trailer sizing as trailers generally run 14", 15", 16" or 17.5" tires while today's HD trucks start at 17" and go up from there.

Rincon, I don't think anyone was saying they used the same size or tread pattern on their truck and trailer. Just that they ran LT's on both. There are lots of LT tires the correct size for RV's. Most of the time they are are a highway rib pattern which is great for RV's.
