20.5 Wheels and tires 

Check at regular intervals that the wheelchair’s tires have the correct tire 

pressure. 

 

Check regularly that the tire pressure is okay. We suggest checking the tire 
pressure at least every 4 weeks.  

Type of tire 

Tire size 

Recommended pressure 

Front tire 

2.80/2.50-4 

35 PSI, 2.4 Bar, 240 Kpa 

Rear tire 

3.00-8 

50 PSI, 3.5 Bar, 350 Kpa 

 
 
 
 
 

 

20.5.1 Puncture repair 

 

Since the wheelchair is rather heavy, it is recommended to let your authorized 
supplier repair eventual tire punctures. First lift the wheelchair so that the 
punctured tire is free from the ground. Both front and rear wheel tires can be 
taken off by loosening the 3 bolts (B) or center bolt (D) which hold the wheels 
on to the wheelchair. 

DO NOT LOOSEN THE CENTER BOLT.

 

 

 

Exploded view of (drive) wheel 

 

 

An incorrect tire pressure may result in lower stability and maneuverability. 
Too  low  tire  pressure  also  results  in  abnormal  wear  and  shorter  driving 
range.
