What brand and type of 13 inch tires are you running? Is there any clearance issues on the truck? That is assuming it has not been raised. Any idea on the RPM drop at 90 KPH? My Carry is a 4 speed 4X4 and it turns 5500 RPM at 80 KPH. I am hopping to get the RPM lower at 90 KPH. The truck seems to have enough power to be able to handle the lower RPMs.
