Comparable Size Bridgestone/Continental tires to 255/80R 22.5

Recommended Posts

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?

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.

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.
