17.5 in wheels and tires

Our trailer weight is just less than 15,000 pounds. We have about 25,000 miles on our G614’s. I ran a year with 90psi in the tires and have some wear on the outer edges, the wear appears to have stopped after going to 110psi. I’m also planning to replace the tires this summer. Based on the weight of our trailer should I stick with the G614’s or should I move to 17.5 rims and tires? We put 8-10 miles on a year.

Thanks

I currently have 35,000 on my Michelins 17.5's and they look good for another 20-25,000. I wouldn't run anything else as experience speaks VOLUMES! I have the Alcoa rims - if you get them also go for the Sure-valve valves as aluminum rims have a tendency to leak around the stems and Sure valve have held the same pressure for a year (120 PSI +- 2PSI).

They sell 17.5" rims with various bolt patterns, mostly 8 lug and set up for dual rear wheels.

If I was to design a trailer, I would use dual wheel type of rim and tire, so that the brake drums or disks are inside the center of the rim, thus less space is required for the tire and axle assembly in the floorplan.

I would also want disk brakes on any fifth wheel over about 14,000 GVWR.

We have about 20k on these G114's and they still look new, but we do have Mor Ryde IS that has been aligned. They were on our previous Bighorn with spring suspension prior to this rig...no visible wear at all. Have no problem with pressure...however pressure will fluctuate with changing temps...that's normal.

We too experienced premature blowout on G614's at only two years. I feel that weight loads close to the tire limit is a factor. These 17.5 tires give more than a 1000 pound cushion on each
tire...the extra security is priceless.

I bought a new 29-5T in March 2013. Pulled it from the dealership in Mesa to my home in East Texas and put new 17.5 wheels and tires on it immediately. After pulling it about 6K miles, I am completely satisfied with the wheels and tires and would definitely do it again. Kinda lightens the hip pocket, but the peace of mind is worth it. Good luck.

Can you tell me about the differences you have noticed? Handling? Wear? Holding pressure?

Thank you!

don't know the answer, how short for the G614's?

We put them on in winter 2011. We work full time and get out in our 37ft Cameo when we can. We estimate about 10,000 miles...and that's conservative.
