tireman9 Report post Posted October 8, 2013 I AM TRYING TO FIND TIRES FOR OUR 1978 ITASCA SUNCRUISER MOTOR HOME...............DOES ANYONE KNOW A TIRE DEALER THAT MIGHT HAVE THEM? That size was declared "obsolete" in 1997. I am on vacation now so do not have acess to my old data books but if you wait till the weekend I can look up the data and give you the specs so you can find an appropriate and more available tire.

tireman9 Report post Posted October 18, 2013 OK Sorry for slow reply. Found my 1977 Tire & Rim Book and it shows for an 8-17.5LT OD 31.02 Section Width 7.85" on a 5.25 wide rim You didn't say what Load Range you have or need but I found LR-C 45psi 1820# dual 2075# single LR-D 60 psi 2155# dual 2455# single LR-E 2460# dual 2795 single. I can help you look for a modern size and Load range but really need to know your current tire loading (or at least the axle loads F and Rear) If you want you can drop me email so we can work this out Tireman9@gmail.com Share this post Link to post Share on other sites
wildebill308 Report post Posted October 22, 2013 You might consider going to the local junk yard and getting a set of 16 in rims for your motor home. You can find many tires that are the same rolling diameter and load range much cheaper than trying to find 17.5 tires. Any good yard will have rims that will fit and be the right load range. If you really want to find 17.5 tires try hear http://www.ricksontruckwheels.com/tires-175-truck.php I could only find 1 Yokahama. http://www.yokohamatire.com/tires/detail/ry103 Bill Share this post Link to post Share on other sites
