4ply or 10ply

Postby Kavonnt » Mon Aug 01, 2016 1:25 pm

Hey guys. I plan to get some Cooper STT Pros Soon and my tire guy asked me a daunting question: 4ply or 10 ply. I do plan to go offroading and exploring every once in a while however my truck is my daily driver. My current tires are 4ply (Yokohama Geolander AT/s 265/70/16). Throw in your .02, thanks.

10 ply are for work trucks and trailers. They will ride horribly on a passenger vehicle and won't flex well offroad.

Yeah? Tire guy said that 10ply rides like a dump truck. Rodeos are SUVs but they're def on the lighter side at barely over 2tons. Thanks for the quick reply

I had 10 ply tires on my 98 Amigo they wore great and rode alright on the road, would feel the road more for sure. Would bounce the car over bumps instead of absorbing any of it. Off road they killed my back, and wont air down.

My new coopers are 3 or 4 ply and they ride much better, feel a lot less of the road in my seat. They handle great offroad, and they airdown alright and grip very well.

I've had 10 ply tires on several lighter SUVs and trucks. Every single one road rougher then with P metric tires. I had to run them at lower pressures on the street and like Egagnon said they don't air down very well off road. On a 2g Trooper I would run E rated tires only because P metric's squat more than I'd like. Really though, no Isuzu passenger vehicle weighs enough or has a high enough GVWR to justify E rated tires. See if you can get the same tire in a LT C or possibly D rated tire. You'll be much happier with the ride and off road performance.

Guess it's down to personal preference, 10ply is just fine for me.

If you want a rolls-royce cushion to ride on then get the lower ply tire.

It has more to do with the vehicle you drive, the load you carry and what you're accustomed too. My 1g Trooper has P metric and I wouldn't go any higher for the load rating. The truck doesn't weigh enough, even fully loaded, to justify anything heavier. On my 2g Trooper I'm not a fan of the P metric tires. The side walls are just too soft for my taste.

Personally I work and drive luxury cars all day at work. Even with my tires aired down I'd never compare how my Trooper rides to one of those cars. I would however compare a 1g Trooper on E rated tires to a dump truck. So I guess if you're used to a truck beating the crap out of you then E rated tires would be fine.

On something as light as a 1g Trooper though they are way overkill. My 1g Trooper tips the scale at 3600 unloaded. I had it on the scales a month or so back. Last time I check 1 E rated tire would be capable of carrying that load and then some. Not really sure why you'd need 16k worth of load capacity on a truck that doesn't weigh 4000lbs.

Load ratings are just one factor.

I run a 10 ply for sidewall strength. The trails in my area are hard on sidewalls to say the least, and a strong cut resistant sidewall (like the cooper 3 ply, BFG, ect) will get you there and get you home. I've tried P rated, C rated, and E rated of similar make/model on various vehicles over the years. Limited success with P rated, somewhat better with C rated (even a 3 ply sidewall set yielded a cut sidewall), and the E's have given me no issues other than a slightly tougher ride. Nicer shocks and the correct springs have helped to mitigate the roughness.

Personal preference and terrain/usage play a big part. Based on the OP's description, no need for an LT rating for his purposes.

No 4 or 10 ply. Those are ancient bias ply designations. P metric as in passenger tire. C,D,E in Light Truck tires. C is fine for 1/2 tons. E (10 ply) is a HD tire for 3/4 and 1 tons. Way overkill in my book on a light SUV. Though folks do run them.

Ancient designations? They seem to be prolific in the tire industry and apply to all tires...

The best overall load rate for your vehicle would be "C" (that is 6ply). Additional bonus would be if the sidewalls are 3plied (vs usual 2 plies). There are a few good tires on the market that provide 6ply tread with 3ply sidewalls.

Well, this can be a touchy subject, but I'll chime in as a happy 10-ply (Load Range E) user. For remote Idaho roads, jagged lava rocks are the norm, and I want the most protection possible. Are they firm? Yes. I generally go with 40 lbs of pressure, which is close to the low end of the recommended range.

This is one of the "YMMV" things (Your Mileage May Vary. In this case, your mileage may actually vary. Like, for real :) )
