Trav's 86' Sunrader Posted March 9, 2009 Share Posted March 9, 2009 Has anyone tried to run these? I have an 86 sunrader and was looking for a more aggressive tire. Quote Link to comment Share on other sites More sharing options...
WME Posted March 10, 2009 Share Posted March 10, 2009 They probably will rub when mounted on duels. The recommended tire is 7.3" section width, these are 8.6" Quote Link to comment Share on other sites More sharing options...
Trav's 86' Sunrader Posted March 10, 2009 Author Share Posted March 10, 2009 It will probably be close, I spent the morning calling tire shops and they just don't make a many LT195's with All Terrain tread. A local shop suggested General Grabbers in 28's and was willing to try them on to see if they rubbed. I will get back to everyone and let you know how it goes.

McShank Posted March 10, 2009 Share Posted March 10, 2009 Make sure you get 8 ply tires, either 185 or 195. Just because the tire says LT does not necessarily give you the weight rating you need. Check out "tires-easy.com" Quote Link to comment Share on other sites More sharing options...
Trav's 86' Sunrader Posted March 11, 2009 Author Share Posted March 11, 2009 It looks like the only option on that site is Yokohama Y356 - Load Range D. Why do you need load range D (8ply)? The tires that were on the rig when I bought and are dated to 92' are LT195 Cooper Discovery Load Range C. These must not be manufacture recommended?

WME Posted March 11, 2009 Share Posted March 11, 2009 185/195 C range max psi 50, max load 1600lb.....185 D range max psi 65 max load 1850.... 27x8.5x14 max psi 50, max load 1500. The question is what does your Toy really weigh and will 3 tires support the load, after a flat?? Quote Link to comment Share on other sites More sharing options...
McShank Posted March 11, 2009 Share Posted March 11, 2009 Load range C are ok on a pickup or VW Bus but your rig probably weighs around 6000#s, most of it on the rear axle. I had load range C tires on mine when I bought it and within several thousand miles the edges were cupping and showing a little tread separation even though I had kept the tire pressure correct. With 8 ply tires the extra 2 plys are on the sidewalls where you need it to support the extra weight. Once I switched, the rear end firmed up a lot compared to the side sway I had experienced. D range street tread can be found with Yokohama Y356, Nanking N810 or Hankook RA-08. I bought Nexen SV820 for more grip in snow and mud since I sometimes camp where access is on county maintained dirt roads that become treacherous with a little moisture. Google "185R14 8PR" and see what comes up. My Nexens were under $70 delivered. Quote Link to comment Share on other sites More sharing options...
Trav's 86' Sunrader Posted March 12, 2009 Author Share Posted March 12, 2009 Well I am fresh from the scale 6020lbs. That is with no people, most camping gear, minimal food, and all tanks at around 1/2 capacity. My rig is a 1986 21' Toyota Sunrader Auto Trans. LT195's are rated at 1900 load range D and 1500 in C. Estimate of wight loaded, 7,000lbs/4 = 1750lbs per wheel wheel; I am assuming that if one tire on the dully blows she still needs to stand thus divide by 4. So there you have it, I should get load range D, damn my vanity of not having an all terrain tire. Quote Link to comment Share on other sites More sharing options...
WME Posted March 12, 2009 Share Posted March 12, 2009 You need to scale each axle ( front and rear) to get an idea of how much weight the 3 tires would have to carry. I would guess the front axle is around 1700 lb and the rear is around 4300 lb. 4300 is to close the max for 3 of the 27X tires. Espceialy if your empty now. The big deal about the 3 tires is most of the 86 Toys have a 5 bolt front rim and a 6 bolt rear. Most of us carry only a 5 bolt spare. We plan on limping into the nearest town and getting a replacement tire, or swaping the tire on the 5 bolt spare. Right now the math says 185 D Well I am fresh from the scale 6020lbs.

Right now the math says 185 D If the issue is the 3 tires, it seems that I should look into a solution that switches the front to 6 lug and put on new rims (I saw another post with adapters for the front). Then all I would need to do is make sure I don't run on three. The places we go are far and it could be a 50 mile dirt road limp to town as it is. I just as soon get a spare for the dullies. Are dullies easy to change. As for the dullies "kissing" as the tire guys put it, I wonder if you can get a spacer like they make for bigger dullies when people add big tires.
