Imelmo,
How extreme are you wanting. I can from personal experience recommend a few different ones but need to know how far you are wanting to go toward dedicated mud or offroad performance?
Many tires companies have cut there choices in sizes in many of their tire lines. This was in many ways thanks to the bone head move by OBAMA with the tire embargo which did nothing but have all companies move to India from China and jacked up pricing and creating a vacuum for at least a year.
I would go with a 33" as anything smaller looks weird IMHO in our wheel wells not to mention these big old trucks bodies.
Point is many of the tires that use to be available is many sizes are no longer offered but in the most popular sizes now.
Such the MT Baja Claw was a great tire for me. But they no longer offer it in a 18 wheel. If you do not mind going to the milder MTZ tire they have a great one that would do perfect on the 18x10
MT MTZ 33X13.50R18 3525lb E rating I ran this size in the claw on my Bronco and loved it. I beat the living crap out of it and it kept asking for more.
There are a few Interco tires that will fit but many are not E rated etc or in your size.
The M16 is one that is more a aggressive all around tire than a "mud" tire. But here the specs which are good and I have these now in 40s.
Interco M-16 33x12.5 rated to 3650lb E Rating and 80psi
If looks matter alot I can tell you the two above look awesome. The Claw would IMO have looked the best but SOL on that.
The Nitto Mud has plenty of history on the Super dutys so doubt I need to say anything. They do get loud on these heavy trucks compared to typcial rock crawler jeeps. They were on a Cherokee and were not bad on the road at all.
33x12.50R18LT E118Q 2910lb@65psi
Then of course you have the tires everyone is running the Toyo MT
33X12.50R18LT 118Q E/10
I guess it all depends on what you mean by "MUD" tire.
But for me I like to have something that first performs and wears well, next looks nasty, and is not something every pimped mall crawler is running. For me I would go with either MT MTZ, Interco M-16, or the Nitto Mud Grappler. They each give a different level of street/mud ratio so there should be something to fit.
oke: LOL
