35's - by the numbers

How is your acceleration now?

First a correction, the toyo diameter should be 34.9 not 35.9 as stated.

More numbers:

2.5 - turns on the torsion bar

23.25" - hub to fender on the front

Only one rub spot on the right front swaybar, but I think it's barely touching since I can't even hear it.

Two additional tanks of gas, 15.61 MPG with about 100 miles hwy, 200 city/mixed and another 15.99 highway trip.

The acceleration difference is noticable, but not horriffic. The biggest thing that I see is really the shift points on the auto tranny. I have tried keeping it in 3rd at points where I see I won't be over 45 mph indicated. The factory shift points were sluggish (early) even with stock tires and the taller tires seem to make it a bit worse. The worst seems to be 3-4 where that kicks in under 45mph indicated and rev's down to 1600 rpm and there is not enough torque. One thing I have noticed and am starting to play with is there seems to be more inertia carried after letting off the gas, so you can let off of the gas earlier coming to a pending stop and forward momentum is carried before having to get on the brake. Overall braking response was essentially unchanged surprisingly as I expected some slight differences with the increased inertia.

I don't know if a 0-60 would give any real information since I rarely go wide open throttle acceleration anyway. I would like to know if anyone has played with shift points which I know hptuners can do, and I think PCM for less can do also.

Also a noticable difference with these tires at 40 psi, much more suspension compression is felt in the cabin when going over speed bumps and the like, even at slower speeds. I kept the 33's at 38 psi and would often take speed bumps faster than you think you should normally without much harshness in the cabin. I may take a little air out and see if mileage numbers are affected much.

Oh yea, got a wheelin trip planned next weekend, so I'll take some good pics of the tires before I head out, and hopefully some good before and after pics on the trails.
