14" GYM tire replacement question

I have GYM ST 215/75/14 on my 2011 Int'l 23' AS and am planning for next year to do some ambitious travel to northern Canada. It would seem from reading the numerous tire threads that an upgrade might make sense. What advice would my fellow Airstreamers give on this topic? I should note that I have had no issues with my current GYMs, granted that the trailer is just 1 year old, but we'll be traveling to the Northwest Territories and really don't want a tire related incident.
Thanks in advance for any help.
John S.

Don't expect a tire made in china to be reliable.

There are actually more good 14" LT tires available than 15" because there are some HD vans that use the 14". Do a search for the size you need over at Tirerack.com just for reference of what is available.

Just checked Tirerack but they list only two tires in my size - my GYMs and something called Powerking. Can I go with another size?

I just did the search also and didn't come up with any more. I must have been wrong. The Power King is from China, but they are the old TowMaster brand, so they might be good. I'd ask around. You could go bigger if you have the clearance.

SteveH, I think the tires you were thinking of are 15" tires. I solved the same problem - upgrading from the 14" Marathons (made in New Zealand) on my 2007 23' with new 15" wheels and Nokian Hakka C Van tires - they were basically made for Vanagons or Sprinters. Continental Vanco tires are the same general idea.

I found it....Michelin makes a 14" 205 load range C tire called the Agilis. It's built for vans.

Agilis | Michelin Tires

Thanks, that looks like the ticket. My only concern is that is
it's a 205 and my GYMs are 215 and it doesn't appear that the Michelins come in a 215/14.

I checked the specs and the Michelins have a load rating of 2145-2266 lbs vs. 1870 lbs for the GYMs. Appears that I'll be looking to upgrade with them even if they are a little narrower.

Good find! Width doesn't matter much here, as both sizes will fit on the wheels.

Your OEM 215/75/14 tires have a diameter of 26.69". The Agilis 205/75/14 have a diameter of 26.14." You'll lose a tiny bit of ground clearance (about 1/4 of an inch), but it probably wouldn't really make a practical difference.

After a lot of consideration I just put a set of 14in Kumho Radial 857 on my 1999 25ft Safari that I bought from TireRack.

I replaced some Duro bias ply tires that the PO had put on.

Tire Specs: No Sidewall Aspect Ratio - The tire is a bit taller than the 75

205R14 Load DLoad Index 109 = 2271lbs (1030kg) per tireLoad Index 107 = 2149lbs ( 975kg) per tireSpeed Rating Q = 99mph (160kph) 109/107Q DMax Load = 2,271 lbsMax psi = 65 psiTrailer Use Only

Going to Yellowstone in a few weeks so it should be a good test.

Happy trails

I thought I'd bump this thread to get some feedback fro JDS and Jackstincan.

JDS, did you go with the Agilis tire? If so, where did you get them? I've looked online and can't find a place that sells them.

Jackstincan, how did your trip go to Yellowstone with the Kumho tires?

Ho'onanea - I am still looking after contacting Michelin directly as well as TireRack & Costco - they are apparently not in production. Still using the 14" GYM's but with a certain lack of confidence. Check pressure regularly and haven't lost any with 3,000 miles on current trip. Will continue to look for another choice to provide greater peace of mind.

All the best,

JDS
