Tyre sidewall strength question

[drive it ...]

I see a few of the "extreme" tyres are going to radials now. Are these a heavier wall construction than a normal mud terrain? BFG make noise about their "tough 3 ply sidewalls" but I've seen those torn out or slashed on bedrock or logs in bogs. So are these radial 117's or TSL's just a heavy tread on a casing like a std radial? Or are they closer to the strength of the crossply versions they started out being?

radial is how the wires in the casing are laid together. the side walls are still nylon and polyester. there is no steel in the sidewall. so if you hit something sharp its guna go thru.

Hi, yep, got that, what i'm angling at is are the "extreme" radials more plys or thicker rubber in the walls compared to a normal MT radial.

MT117 comes in 3 flavours (unless changed in the last few months):

MT117 Sport which is a radial
MT117 LT same tread as above but crossply
MT117 Extreme - more aggressive than both above and crossply

Also MT117ex, radial with traditional mud tread pattern.

radial is how the wires in the casing are laid together. the side walls are still nylon and polyester. there is no steel in the sidewall. so if you hit something sharp its guna go thru.

There are some tyres made with steel in the sidewalls, usually for heavy off and on road vehicles. Fairly uncommon.

Check this site out it has some great info. You will find most the tire on the nz market rate highly.

Cheers for answers guys. Been googling myself and quizing a few tyre shops. Guts of it is that a radial silverstone or swamper has pretty much same sidewall casing as a BFG or similar (3 ply sidewall). Other MT's are only 2 ply sidewall.
So a crossply is the only way to get a really stronger tyre. Guess I knew that, just hoped there was something in between.

Central Otago for Christmas - more trails than you can read off a map and neat old gold mining history too. Have a Merry, etc.
