Start with the awkward part

The Goodyear Wrangler MT/R with Kevlar is, in LT285/70R17, effectively gone. America’s Tire’s product page says “Product has been discontinued” with no price. Quadratec says “This product is no longer available” and no longer lists the size. Tires-Easy says the line is unavailable. Tire Rack’s page 404s. The one retailer still listing a price has it out of stock.

The Toyo Open Country M/T is in full production, in two load ranges, at four retailers quoting $410 to $432 per tire.

If you are replacing four tires, that ends the comparison. If you have three good MT/Rs and one destroyed one, you have a sourcing problem rather than a choice, and the rest of this page is about what you are losing.

What the Goodyear does better

It reaches its 3,195 lb rating at 65 psi. The Toyo’s Load Range E needs 80 psi to carry the same load. Same capacity, 15 psi less pressure — which on a heavy truck is the more comfortable way to carry it, because the casing does more of the work and the air does less.

It is also lighter, at 58–60 lb against the Toyo E’s 63.7 lb, and that mass is unsprung and rotating. Sources disagree on the exact figure — America’s Tire says 60 lb, tiresize says 58 — so treat it as roughly four pounds a corner rather than a precise number.

And Goodyear is the only manufacturer in this pair that quantifies its sidewall: a three-ply construction with opposing cord angles, DuPont Kevlar and Durawall compound, claiming a 35% improvement in sidewall puncture resistance over the previous Wrangler MT/R. That is measured against its own predecessor, not against Toyo, but it is a number.

What the Toyo does better

Load range flexibility runs entirely Toyo’s way. The Goodyear is Load Range D only in this size. Toyo offers a C — 2,755 lb at 50 psi, 116/113Q — which is what a Wrangler, Gladiator, 4Runner or Tacoma owner should usually want, because those vehicles will never put 3,000 lb on a corner and the lower-pressure casing rides better. It also offers an E for three-quarter-ton work. There is no Goodyear equivalent at either end.

Toyo also sipes the tread blocks deeply, a wet-road feature the Goodyear does not advertise, and adds over-the-shoulder tread for deep mud. Tread depth is a wash at 18.9/32″ against 19/32″.

A speed-rating detail worth catching

Toyo’s Load Range E in this size is rated P — 150 km/h, about 93 mph. The Load Range C is Q, about 99 mph, as is the Goodyear. Buyers routinely assume every mud-terrain is a Q. Choosing the heavier-duty Toyo casing in this size actually lowers the speed rating, which matters if you tow at highway speeds in hot weather.

What neither of them gives you

No mileage warranty, from either. No UTQG grade — light-truck tires are exempt. And no three-peak mountain snowflake: neither is severe-snow rated, whatever the tread suggests. Toyo’s own warranty page offers a 500-mile, 45-day trial and a limited warranty, and nothing about treadwear.

One disclosure oddity: Toyo’s Canadian site describes the Open Country M/T as a “high turn-up, 3-ply polyester casing”. The US site says only “high turn-up, tough polyester construction” with no ply count. Same tire, two different levels of disclosure.

Which one to buy

Buy the Toyo, and pick the load range deliberately rather than defaulting to E. If you specifically want the Goodyear’s Kevlar sidewall and lower working pressure, check whether your size is still made before you plan a build around it — several sizes remain, but this one does not.
