Replacement tire for the Chinese OEM rubber

My 35 foot Keystone Bullet bunkhouse is less than 2 months old and has about 500 miles on the 205/75/R14 OEM tires. I've been reading that tires are a second thought with most manufacturers and ultimately, trailers are equipped with cheap Chinese rubber.

Since I'm planning some longer trips later this summer, is it worth buying some more appropriate shoes for the TT? I'm bummed that I don't have 15 inch wheels to begin with. But am more concerned about mitigating a catastrophic blowout 10 hours away from home.

Etrailer has some good reviews on 14 inch D-rated 8 ply tires; I think Karrier is the brand. Load ratings go up over 2100 lbs.

I know many on these boards talk about Maxxis's and Kumho's. And I read that upgrading to a d-rated tire with higher max pressures on the OEM wheels can cause failures in the alloy material of the wheel itself.

I just want to play it safe at 65mph. Any recommendations appreciated.

    Seems small for 35' What is the trailer GVWR?


    Gvwr is 7600 lbs. Dry weight was 6100. Keystone keeps 14 inch wheels on floorplans that gvwr stay below 8000 lbs. I'd like to upgrade to 15's and I may do so. But, I really need to decide 2 things, do I do it sooner than later? And is it worth the extra investment in 15 inch wheels? I'd have an extra set of wheels lying around if I did the latter.

    I suspect that looking for a coach with 15 inch tires is easier before you purchase something. Maxxis tires appear to be well received in all sizes so you can stay with the 14 inch and have some peace of mind. Virtually all rims are strong enough to go to a D rating but that is something to check into with your tire shop. Since tires are also rated on pressure it is possible you would never need the max pressure for a tire that has a D rating for your coach.
