Hello all,I have a 2000 model 4wd TF rodeo with standard 16 " rims I am trying to reduce my engine revs at 100 klm (currently@2750 rpm) Has anyone out there fitted larger wheels to this type of 4x4? If so I would like to know what size rims and tyres you used and what the engine revs droped down too. Many thanks.

I've got a 1997 Rodeo (same shape as you with 2.6L petrol 4cyl). I changed the stock 205/75 16 tyres a while ago for 225/75 16 on the same rims. With the 225 tyres I was running at 100km/h@3000rpm. I have since changed those for a set of 31in tyres on 15in rims. I now sit on about 100km/h@2800rpm.

However not all tyres are equal. My 31in tyres measure 30in tall.

Try some of the engineering mobs that advertise in 4WD Monthly. A few of them do overdrive kits that can help. That way you don't lose torque through the tyres being too big and your speedo will be acurate.

fitting 31x10.5r15 or equivelant diametre in 16 inch will drop about 100rpm. get a brochure from a tyre dealerwith rolling diametres. ive run 265/75/16 and you gain more but not without body/suspension changes to make them fit. then there is insurance, roadworthy, and speedo to think about.
regards peter

try this if it works photo

I had 31" BFG muddies and they were a large 31" tyre. Can't remember what revs the engine dropped down to but there was no significant change to fuel ecconomy as a result.
