10R22.5 on a 4104?

[gulfyankee]

Is this acceptable?

[fe2_o3]

I would think not..Depending on your weight. The smallest I'm willing to go is 11R 22.5 front and 11R 20 rears. I weigh 27k and change..Cable

Don't forget about the RPM difference

[WEC4104]

Based on the tire circumference difference, your top speed (up against the gov) will be 3-4 mph lower. Most 4104s don't have a lot of extra top end speed to give up. You might find it difficult to keep up with the desired traffic flow. Fuel economy may also drop a bit.  Hill climbing a slight improvement.

You need to find out the weight rating of the 10" tires then decide. The original size was a 10:00 or 11:00x20 bias ply tube type (not sure and too lazy to go outside to look) but don't know the weight rating.

A normal 4104 conversion runs around 20 - 23,000 lbs unless you happen to have something extra heavy like a large golf cart battery bank.

You won't miss the top speed, 4104s are not speedsters anyway. Hill climbing will improve, something most 4104s can use.

10R-22.5 is basically in the 9.00-20 class.
I'd say it's most likely too small for most 4104 purposes.

10R-22.5 is the same diameter as the 275/80R-22.5 tire. There is a F & G (12 and 14ply) rating on this tire.  With the G 14 ply tire you could have 11,350lbs in the front, and 21,420lbs in the rear.  I could run these tires since my bus is 10,500lbs in front and 20,500lbs in the rear-but I stay with the 11R-24.5 for the height and slower rpm (476 vs 517).  If you have a good deal on 10R-22.5's and you weigh under the capacity-go for it.  These tires are Michelin XZE's.  Good Luck, TomC

Thanks for the replies. I'm not worried about top speed, on the 2 hour drive down here it easily hit 65, and seemed to have more to go. 65 is fast enough for me. I've already purchased 2 practically new ties for $100 each, and have found some more for $125 each, hence why I am asking this.

[gulfyankee]

Ok i looked and the tires are rated for 5600 lbs each.

Me I think the width of the 10r tire would kill the the driving and steering on a 4104 plus the high air pressure it would require for the weight I presume that is a 10 inch wide tire and will it work on 8.25 wide wheels ?

good luck

Scott-good then they are the heavier duty 14 ply rating.  The max tire pressure on that tire is 115psi.  Most wheels are rated to at least 130psi, so you should be OK.  Biggest factor in ride quality is proper tire inflation.  Still-make sure you weigh front and rear axles so you can run exactly what the manufacture recommends.  If you regularly cruise over 65mph, then add 10psi.  Good Luck, TomC
