hi ,

I am planning to fit 9.00 x 16" NDMS tires on a SWB Jeep. If you are wondering what tire this is, it is the one fitted on JCBs front wheels.

Wondering what kind of issues/performance I can expect. I could think of the following issues :

1. Need wider rims ( 6 to 6.5" width instead of the present 4.5")to fit the tires.
2. Need to increase clearance height to compensate for the bigger tires.
3. Better fuel efficiency due to large diameter of tire ?
4. Poor fuel efficiency due to heavier tires/rims ?
5. Poor braking due to bigger tires - Need to go for disc brakes.
6. Poor Pickup... Will the vehicle atleast move normally?

I am not in a position to fit the tires and then check out the performance. It would be better to at least in theory analyse it and then go for it...( if it makes sense...)

BTW it would have a Peugeot DI diesel engine, 5 speed gear box, 4x4, Free wheeling hubs, etc.

Regards
Anand
