gs311 Posted August 2, 2015 Report Share Posted August 2, 2015 What is considered the min. distance between tires on a single wheel tandem axle trailer? Have about 2 1/2 inch now but want to change to G614 tires that are a 1/2 inch taller. That would leave me only 1 1/2 inch separation, is that enough?

Mark and Dale Bruss Posted August 2, 2015 Report Share Posted August 2, 2015 That would be pushing it. The wheels move for and aft a bit as they swing on spring action. What size are you changing from? Are you expecting to inflate the G614'ss to 110 psi? Because many trailers with E load Rated tires have rims only vertified to 85 psi.

Randyretired Posted August 2, 2015 Report Share Posted August 2, 2015 The tires on our Teton are only 1 inch apart. Been that way since new (1999). No problems. Randy 2001 Volvo VNL 42 Cummins ISX Autoshift Link to comment Share on other sites More sharing options...

reed and elaine Posted August 2, 2015 Report Share Posted August 2, 2015 Would worry about tires touching on sharp turns and causing carcass separation. We have this problem on our Open Range 337RLS and could not use the Michellins we wanted. We are still almost 3000 pounds under max.

TXiceman Posted August 3, 2015 Report Share Posted August 3, 2015 Do not have a problem with tires getting that much closer with the Mor/Ryde IS suspension. G range tires on 16" rims and just over an inch apart.

Ray,IN Posted August 3, 2015 Report Share Posted August 3, 2015 The minimum is 1.5" between tandem tires. A tire can "grow" as much as 3/4" in diameter when at running temperature and at speed. I went to Sailun S637 235/85R16, LR G tires on our 5er and had to have both axles moved farther apart (2.5") to prevent contact while maintaining the 60/40 weight ratio. The time and expense was well worth the cost IMO, I never had another tire problem. Aluminum rims have the maximum air pressure rating cast into the back-side of a "spoke". Steel rims have it stamped into the inner rim, hidden by a mounted tire. 2000 Winnebago Ultimate Freedom USQ40JD, ISC 8.3 Cummins 350, Spartan MM Chassis.

Randyretired Posted August 3, 2015 Report Share Posted August 3, 2015 3/4" tire expansion is 3/8" on each side or 3/4" total expansion between tires. Our 5er came from the factory at 1", the minimum recommended by Dexter. We run XPS Ribs and have never had a tire fail. 3 axles.

gs311 Posted August 4, 2015 Author Report Share Posted August 4, 2015 RayIN -- Good info on pressure stamp location, will check my spokes. Looks like I'll be good if it's an inch or more.

jamtracy Posted August 4, 2015 Report Share Posted August 4, 2015 Tires now are Akuret ST235/80 R16 Load E. Have been told by Columbus camper group that wheels are rated at 110psi. will have tire changer make sure if I go this route. The G614 tires are not the a 1/2" taller. Go to Goodyears website. The G614 has the same diameter as the ST235/80R16s. I know this because I put the G614's on my 5th wheel a couple of months ago and I had the same tires as your current ones and the gap didn't change. I keep a 100 PSI in them. I did a lot of research and I new I was going to get these tires eventually. But after I had a blowout I got rid of those china bombs. I was hoping the Akurets would last a little longer but that didn't happen. I did install a TPS system with these tires.

gs311 Posted August 4, 2015 Author Report Share Posted August 4, 2015 Thanks James, that makes me feel even better. Was going by what my tire guy told me. At my age I should know to do my own research. Gene and Jane 05FL-Century 10 speed Manual 2013 37ft Forest River--Columbus Link to comment Share on other sites More sharing options...
Mark and Dale Bruss Posted August 4, 2015 Report Share Posted August 4, 2015 If you need to replace rims to get 110 psi rating, you should consider getting 17.5" rims. A 215/75R17.5 has the same diameter as a G614. You would have more choices of good brand tires. Also, as an example, the G114 (215/75R17.5) is lower cost that a G614 because of greater usage in the trucking industry on electronics vans.

jamtracy Posted August 4, 2015 Report Share Posted August 4, 2015 Thanks James, that makes me feel even better. Was going by what my tire guy told me. At my age I should know to do my own research. My pleasure. I checked the inside of my rims to make sure they were rated 110psi. If I had to replace the rims I would have done what Mark said. I like these tires they look and feel great.
