I looked into this about 5 years ago. What I concluded was: Duro, Maxxis, Denman (in that order) are OK. Goodyear Marathons are variable. Carlisle not recommended (Carlisle also owns Titan. I've now had two sets of Duro DS2100 ST175/80R13 tires, and have had no problems.

Apologies if this has been already discussed-to-death....

I need to replace the tires on my Cobra trailer, including the spare.

Any glowing recommendations for the best ones out there?

Size 175/70 r14

I'm actually having a little trouble finding that size at the local dealers....and I'm tired of telling them I don't want polyester, non-radial tires!

So....what's your favorite tire that is dependable, smooth riding.....etc??

Thanks,
