Tires

Toyo M/Ts are E rated at 3900lbs and much better quality than any BFG...

Anyone that takes a 11000lbs vehicle hardcore 4x4 should have an E rated tire.




Cheers

Stainless Steel Brakes (www.ssbrakes.com) is one that comes to mind.

What my new SMB is coming with

I pick up my new SMB tomorrow, Friday November 30th. The plan was to have the vehicle complete and ready for off-roading. Our intent is that this vehicle will be used for transportation to and from our off-road adventures so I tended to have it designed and equiped siding with more of an off-road than highway slant.

After investgating tire options based on a vehicle weight of 9000 lbs I went with the following., I also depended on what he SMB people said would work best with the new axles, brakes and wheel well size.

Cooper Discoverer STT LT325/65R18 "E" rating. I needed a wider tire for driving in the sand and with all the weight of this vehicle I believe I will need the extra tire contact patch. We will see..

Thanks,
Fred

Went with a replacement set of BFG All Terrain T/A KO's earlier this month (285 75/16's). Ended up with E load rated tires, as oppossed to the D load rated tires that were taken off. I think the van has less sway now, though that's subjective, and it's comparing the new tires to the old (D load) tires with 36,000 miles on them.

The max load on these tires is 3750lbs, as oppossed to the 3305lbs of the D rated tires (at a lower PSI). It appears these size tires have the largest load rating of any of BFG's tires. Interestingly, there's a small tire diameter difference (0.2") between these tires according to the BFG website.

Fred,

Those are the same tires that we have been talking to SMB about. You are going to have to post some photos and then a review after you get a few miles on them.

We have continued to do research for our tire selection.....

This past weekend we had the opportunity to chat with an aquantance that has been in the tire business for 40+ years (and his family has been even longer). This chance popped up because we had to have a small piece of metal removed from on of the tires on our Prius.

We were talking about the requirements I have for the tires we want on the SMB, and what options we might have.

As we were wandering around, he showed me some older tires and explained that due to cost reasons that many larger tires are no longer being built with "steel" carcasses but are now being built with "polyester" carcasses. I said "huh?".

He explained that in the past we not only had steel belts under the tread, but also in the sidewalls. The he said gave the older tires much more strength.

He also explained that in the past there were many more choices for 16inch wheels and that it was the advent and adoption of larger wheels which has helped lead to the move from steel to polyester carcasses.

He said that the place where they are getting the most complaints are the farm and ranch folks where there is much more offroad and weight issues for tires. (sound familiar??)

I asked him specifically about the Cooper STTs that we are looking at and he worries that we could get a bad wear pattern with onroad driving, but agreed that it would meet our other needs. He pointed out that the STT has more plys in the sidewall than other tires of similar size.

I wanted to share this due to the number of discussions that we have seen about blowouts and sidewall issues.

It seems to me that with the polyester carcass that when airing down there will likely be much more sidewall flex...and thus more heat and more aging.

Anyone know of any tire manufacturers still using a steel carcass?

SMB on order and van delivered (we think)

Additional research results...

We continue to see that for a 35 inch tire, we are finding the best load carrying when using an 18inch wheel; we are finding few to no selections for 17 inch wheels.

We continue to see that if we were to increase to a 37inch tire we would have more selection for 17 inch wheels. (but that size requires SMB body mods)

We did find some 35 inch tires that would meet a higher E range load capacity that we are looking for at Dick Cepek (more than a couple) and Mickey Thompson (only a couple).

This leads us to think that by going to an 18 inch wheel we will have greater tire choices that meet our requirements in the future.

Do you know if you can fit 35" tires on the SMB 4x4 without modification?

Yes.

35 inch is the max size without body modifications.

We are getting 35 in on ours (2008 Ford EB 6.0PSD SMB4x4).

They seem to have no issues installing 35 inch tires.

They balk at 37.
