I will post this again since Brian is more interested in BIG ASS Tires... 
Looking for info on these tires purchased recently and how you rate them.
Nexen SV820's
Hankook RA18s
Vanco 2s
I have Vanco 8's on my Bus but,they are getting old and i need to replace
them.....I don't drive the bus many miles per year.
Thanks. Chris

What tire pressure are people running on their grabbers. The 20 7X8.5 14s, that is?

| Start with the stock pressures. 30 up front and 44 in the rear. |

So, what (if any) of the newly available tires has anyone tried and liked or disliked?
I've seen some Ranger/Thunderer brand, I think in 185R and 195R-14 sizes. several others.
Last summer, I bought a set of Goform brand 185R-14 from Tires-Easy $282 delivered in Iowa.
I put them on my 71 Dormie, which was basically sold, so I only drove them perhaps 100 miles. they looked to be a commercial/ highway mileage tread, not so much an all weather tire. But they looked the part and drove very good for what I could tell.
I have Vanagons, a bay or two, and a couple splitties, so whatever tires I buy can be moved to any of these 3 models, with some rim changing.
I need to buy some very soon.
that would be my main use- highway miles good conditions.

Is that what the sticker on a 77 says for tire pressures?

I did and I'm at 44 and 30 - but that's based on a stock tire size. While they are the correct rating, grabbers are not that size.

Surely you don't expect the tires that came on that shiny new 77 Westy are built with the same design/materials/technology as what is available today?
I am not a tire engineer, but I am confident there is an obvious difference in tires made today compared to those made 40 years ago. Are you?

If I go by the recommended tire pressures on my 68 single cab with Wrangler HT's, or my 70 camper with BFG's, the steering is way too heavy. 28 PSI may have been great with the rock hard rubber compounds back then, but not anymore.

hmm.. well, on my vanagons the stickers show that different tire sizes (185 and 205) require different pressures that range as much as 10 PSI. Yeah, a vanagon isn't a bus... but the principle would be the same.
so...
I'll ask again: what pressure are people running their gRabber AT 27s at on their buses.

That sticker might just be a little irrelevant. There is not a single place in the US you can buy a 205/70R-14 6pr load range C tire. Nobody has sold "C" rated tire 205/70-14 in a decade.
The higher aspect ratio tires, there are MANY RATED tires with enough load rating to carry a loaded type 2. (they are always labeled 185R-14. I do not know why, but in that size they do not label the aspect ratio, so it is understood to be "80".)
The inflation always seems to work better for me if kept in about the same front/ rear bias. If you put as much air in the front as in the rear, the contact patch in front will be much smaller than the rear and the front end will be skittish.
Next time you have some spare time and a crosswind, try some experimentation yourself. Start out with equal pressure on all 4 tires, make a pass each direction, then drop the front pressure about 4 lbs. Try it again. I think a bay usually works best with about 10 more psi in the rear than the front.

Agreed you are comparing apples ("commercial" 6 ply rated tires 185R14Cs good to about 65 psi) to oranges (205/70/14 passenger tires although they are extra load and may be inflated to about 42 psi).
It is not the size, it is the meat. |

I believe the Grabbers to be very similar in construction to the BFG's. Given that possibility, I am running 40 PSI front/45 PSI rear on my 70 camper with good results on my BFG's of the same size. I have run them both as much as 10 PSI lower, but this seems where the bus is most happy.

Thank you. This is the type of feedback I was looking for.

I am guessing they won't be that great in the cold, dry snow you get in Great Falls. If you're gonna drive it much in those conditions, you need some real snow tires. The grabbers will be excellent for the other three seasons, though.
