I believe the tire size would be correct from the dealer but anything is possible. When I added air to the rear tires yesterday I tried coasting in 4WD with the clutch in and it worked much better than with the lower pressure. I think my problem was that I just did not have enough air in the rears thus changing the height of the tires and the ratio ti the front tire height.
You are correct.

hey,
i have read your whole post and i have got your problem the thing you have to do is just dont drive in the first gear more because the model burns more fuel in the first gear and less average just drive in the second if you have any issue kindly post it i will help you out if i can

Suggest you rule out a draging brake. Drive it for a while in 4WD and check the brake drum for heat with your hand
Cheers

I just thought that I would pass on a trick that I have been using for many years....

To find the true rolling diameter/circumference just place the tire on a flat level surface while installed on the vehicle at the correct operating weight and air pressure. Take a piece of chalk or anything else that will leave a mark on the flat surface. Roll the vehicle forward or backward at least one tire revolution and measure the distance between the two marks on the flat surface.

This will give you the exact rolling circumference of your tire,

Check the front and the rear tires the same way and get out your calculator to check the ratio....

Hopes this makes the process easier,
Bob

That's a good, no-nonsense way to figure the circumference, Bob. Thanks for sharing!

That sounds like a great idea! Thanks for that info.
