JaySam Posted October 29 Share Posted October 29 I'm going to be ordering some new tires for my rig here soon and currently it has 195r14 tires on it but I know stock they came with 185r14. Is there any reason I should switch back to the smaller tire? Quote Link to comment Share on other sites More sharing options...
Ssunrader Posted October 30 Share Posted October 30 The load rating is going to be about 400 pounds per axle difference between the two sizes. 1870 vs 2090 pounds per tire. The trucks came from Toyota as a bare frame so the 185 tires were fine for that, I would stick with a larger tire myself. Quote Link to comment Share on other sites More sharing options...
IdahoDoug Posted October 30 Share Posted October 30 Either will handle the rear axle loads fine. Even the lower rated 1870 tire X 4 is good for an axle bending total of 7480 on the rear axle alone. It's key to know that even though the trucks came from Toyota with a bare rear frame (a Cab Chassis), the tires would have been rated for the expected max GVW of the vehicle. Which as we now know, the coach makers immediately blew past and overloaded the axles they ordered from Toyota..... Quote Link to comment Share on other sites More sharing options...
JaySam Posted October 30 Author Share Posted October 30 Ok thanks for the feedback, I think I'll stick with the larger tire then if there's no reason to go back down. Not worried about the weight, it's sitting at 4800 with water and gas full. Quote Link to comment Share on other sites More sharing options...
IdahoDoug Posted October 30 Share Posted October 30 (edited) I think I got 185s as I was worried the larger tires were close enough on the duals to trap small rocks that can tear up the sidewalls. Too cold to run out n check, but I think that's what I did.. Edited October 30 by IdahoDoug Quote Link to comment Share on other sites More sharing options...
linda s Posted October 30 Share Posted October 30 Some of the early Winnebago's came from the factory with 195's so I don't think rocks are an issue. We used to recommend the 185's because 195's were very hard to find with a D load. Seems to not be the case anymore but I still think if you are in serious need of a tire in the middle of nowhere the 185's are going to be easier to find.

Ssunrader Posted October 30 Share Posted October 30 I may want to take careful consideration of what others have said also before making a purchase. 185 is the default size for a large number of small busses that use this size in Asia, are much much more common. If for any reason your tires in back get low on pressure or the vehicle is overloaded, the chances of them rubbing together and blowing out is likely higher with the larger tires, so the ratings on paper may not be realistic in practice.

linda s Posted October 30 Share Posted October 30 We run our tires at much higher pressure than needed. Load Inflation Table - 185R14 - Load Range C & D Inflation (Psi).... 26 ... 29 ... 32 .. 35 .. 38 ... 41 ... 44 .. 47 ... 51 .. 54 .. 58 ... 62 .. 65 Singe (Lb)........... 1080 1147 1213 1279 1345 1400 1466 1532 1599 1665 1731 1786 1874 Dual (Lb)............. 1036 1102 1158 1223 1279 1334 1389 1455 1521 1588 1643 1709 1764 I've had lots of flats and never had a problem with damage to the other tire.

JaySam Posted November 1 Author Share Posted November 1 Cool thanks for the feedback on that. Next question: Which tires do people mostly recommend? I'm looking at the Hankook Vantra, Thunderer Ranger or the Haida Strong 717. Does anyone have any experience with these or feedback on any of these tires? I tried searching but couldn't find much on tire models, mostly just size and where to source. Quote Link to comment Share on other sites More sharing options...
MaineJed Posted November 1 Share Posted November 1 I’ve had the Thunderer on ours for 15k miles with little wear. Quote Link to comment Share on other sites More sharing options...
