bburns8 Report post Posted August 16, 2016 I looking at replacing my tires on my 2001 Fleetwood Discovery MH. The tire size recommended for my MH is 255/80R 22.5. Is there a comparable size in Bridgestone tires and Continental tires that would fit my MH? __________________ 2001 Fleetwood Discovery 37' 330 CAT HP, Freightliner XC Share this post Link to post Share on other sites
wolfe10 Report post Posted August 16, 2016 Closest is 265/75R22.5. You will need to look at all the dimensions to verify that they will work for you. Share this post Link to post Share on other sites
hermanmullins Report post Posted August 17, 2016 Sorry but I'm confused. Don't Bridgestone or Continental make a 255/80R-22.5 tire? Herman Share this post Link to post Share on other sites
wolfe10 Report post Posted August 17, 2016 The 255/80R22.5 is pretty uniquely a Michelin size. Same for the 235/80R22.5. Share this post Link to post Share on other sites
hermanmullins Report post Posted August 17, 2016 Oh . Another question, 12n-22.5. What size are they compared to? Not sure I have the correct numbers. Herman Share this post Link to post Share on other sites
kaypsmith Report post Posted August 17, 2016 My last coach before the conversion was a Sportscoach on Spartan chassis, it used 255/80R22.5. Only manufacturer I could find for this size was Michelin, I was unable to locate Michelin when needed. As a result I went to 265/75 as Brett suggested, exact same height and 10 mm wider, that's just under 3/8 inch in width which means that the duals are 10 mm closer together. On that coach there was no problem making the changeover, ie. no kissing. Herman,12 R 22.5, I have found that 305 is pretty close to 12, I'll have to check the height for comparable.

tireman9 Report post Posted August 22, 2016 According to published standards Michelin 255/80R 22.5 OD 38.2 Width 9.9 Rim width 7.5 to 8.0 Min Dual spacing 11.2 Single load 5205/110 lbs/psi 75 mph max The closest match would be a 265/75R22.5. Here are the specs on the Bridgestone R250F 265/75R22.5: OD 38.4 Width 10.2 5205# @ 110psi Couple of other options, that are not as close: Firestone FS560 275/70R22.5 OD 36.7 Width 10.3 Rim width 8.25 Min Dual spacing xx.x Single load 5510/120 lbs/psi 75 mph max Firestone FT491 275/70R22.5 OD 36.3 Width 10.4 Rim width 8.25 Min Dual spacing xx.x Single load 5510/120 lbs/psi 75 mph max Firestone FS561 10R22.5 OD 40.2 Width 9.09 Rim width 7.5 Min Dual spacing xx.x Single load 5675/115 lbs/psi 75 mph max Continental CCHA3 275/70R22.5 OD 37.6 Width 10.8 Rim width 7.5 to 8.25 Min Dual spacing 12.4 Single load 6940/130 lbs/psi 75 mph max Be sure to confirm the Minimum dual spacing with the tire dealer as you want to be sure the rear duals do not "kiss" +++++++++++++++++ 11R22.5 are about 41.5 OD 11" wide so likely too big.
