    In Jan 2000 I bought 4 33 12.50 15 Mud kings by BFG. I bought 2 brand new and 2 that the tire shop had used. Well in Jan 2001 I was under the Blazer changing my oil and noticed a litlle split in the middddle of the tire. It almost looked like someone took an exacto knife and cut a 1/4 inch slit. It was that small. Well upon further inspection I noticed that there were several slits all the way around. It looked like the tire was coming apart like a bagel. Well I took it back tothe tire shop and I had them replace them. It only happened to the tw new tires not the used ones. They gave me two new tires and here we are a month later and the same thing is happening again. Now they said that they won't order a third set because that their policy. So now I'm gonna be stuck with 2 different tires o my truck. It's not a show truck, but haveing 2 different tires?!! YUCK!!!! I guess I'll have to save my pennies and buy two matching ones. By the way I'll be getting the BFG MUDS. I just have to pay the difference which is 40 bucks.

    I replaced my Cepek's with them due to cost. I couldn't afford the $300 a piece Cepek's....I have the same size as you do- the 33x12.50x15''s. I've had mine since October of 1999 and haven't have a problem with them.....

    I have a set of 4 and all 4 have cracks in between the treads. They are about two and a half years old and maybe 4000 miles on them. I just figured that they were dry rotted since I hardly use them.

    Thanks for the tip, I have been considering them for my truck...
    Now I think I'll go with BFG MTs.

    I'd contact BFG and see what the say about it. If there is a problem with the safty with the tires they should replace them no matter what.

    Aren't mud kings by Wild Country??? If they are from BFG I'd be surprised...but I could be wrong. The cheap wild country, mud kings, generals, etc are cheap for a reason... One they usually don't wear all that great, they also are very weak in the sidewalls compared to say BFG MT's. Also seeing a ton of them in the shop... when they wear down they like to cup and ply seperate very badly. But a lot of wear and tire problems are related to rotation... I rotate mine every oil change using slide the back 2 straight up and cross the front two when moving them to the back. My last truck had some no-name Hercules 33's on it and I nailed out almost 40k w/ this procedure and they still had 6 or 7/32's left. Just my thoughts on it... For the Blazer I just picked up 35" Pro Comp MT's... Look sweet! Although a bit disappointed in the sipping... not very deep... could of grabbed BF MT's for about 120 a piece instead of 160 a piece (w/ one free and like 140 in shipping...[​IMG] from 4wpw...[​IMG]). But live and learn...

    I've had the General Grabber MT's in a 35x12.5 as well as the BFG's in a 33x12.5 on my truck. By far I thought the Generals were a better tire, for ride, off-road traction and wear. I have about 35,000 miles on the Generals and they still have about 40% left on them. Not one flat or sidewall puncture. The generals dug harder than the BFG's and also rode quieter on the street. I certainly don't consider them to be a 'cheap' tire in any derogatory way. If General made a tire bigger than 35" I'd happily buy another set...
    I have 36x12.5 Swampers on now, I'm saving my Generals for long trips and towing.

    BTW, I've also had a set of Mud Kings on another truck but only had them a year before I got rid of the truck. They seemed good and never had any unexplained cracking while I had them.

    From what I've heard it is kinda hit or miss w/ the Generals, wild country tires, etc. Overall most problems happen after 50% tread life, but most times mine are a spare tire or replaced by then anyways. I've never been one to keep marginal tires on... especially on an offroad vehicle. I also have never been a huge fan of the BFG MT's... great of road, but man they roar on the freeway... Heck if they are gonna be that loud I'd rather get SSR's, Baja Claws or Goodyear MTR's [​IMG]! Trying the pro Comp MT's as a last change dance kinda deal... But I really wouldn't hesitate to pickup Generals. Wild Country I try to stay away from...yuck. Just my opinion... I'm sure at least a few are running them very happily.

    I am pretty sure BFG and mud kings are the same tires and made by the same people. Get Generals. They hold up awesome!

    Tires (especially the more budget friendly ones) can be a bit of a hit and miss sort of thing. I did have good luck with my General's though. The only issue I had was their optimistic size claims. I kinda figure a 35"x12.5" tire should be 35" tall...
    At least the Swampers I have now are real close to what the sidewall says[​IMG]

    Okay Rene...how tall ARE my 35/12.50-15 Grabber MT's anyway? Moved up from a set of short 33's and thought they looked at least a LITTLE bigger. Gotta get a few bucks ahead and get another set of TSL/SX's.

    My General Grabber MT's were 33 1/2" tall with about 40% left on them....
    Don't feel bad my 33" BFG's were only 31 1/4" tall.

    Just for comparison my 36x12.5 TSL's are 35 1/4" tall and they've got about 40% left...at least thats pretty close to advertised height.

    Uniroyal, Michelin, and BFG have merged into one company and they make the sport king A/Ts and Mud Kings. I install these tires for a living and have seen no problems. That doesnt mean there cant be problems. I assume you keep your pressure below the rated psi. For that tire it should be 50lbs. Overinflating could have caused this. Personally, I would go with the BFGs though. There a proven tire and the Mud King is relatively new. Just my $.02.

    Yeah, whats up with that? Stated and listed tire sizes? Why dont tire manufacturers stamp what the ACTUAL damn tire diameter is instead of misleading everybody?!?! I run 35's on my 85 K30 and the dang things are closer to 33 to 34 rather than the stated 35 inch. This pisses me off!

    Are you guys measuring how tall the tires are when they are ON the truck or off? Cuz that would obviously make a difference.

    Put mud kings on a 78 k10 about 4 years ago and 25k no problems and pretty good wear.

    On measuring a tire, remember that a company may have used a different size rim to measure from. If you have a narrow rim, the tire will be taller than the same tire on a wider rim. And lets not forget air presure. You might be able to get the actual measuring specs from a shop or call the manufacture.

    I read recently that tire companies do those specs at 80 psi, unmounted on the truck, so that might explain the overestimated numbers.

    I guess I just had a bad "batch"? I wrote to BFG explaining my dilema. Let's see what they say. Thanks for all the great info Guys and Gals.
