Hi guys, I'm new here and just bought a 2003 Astro. I'm looking at tires and wheels for it. The van will have Journeys 3-5 kit on it.
I'm wondering what offset and backspace I need, and should I stay with 16" or go larger? Wanting to put as Tall of a tire as I can and not rub off-road.The van will mostly be on pavement, but when it is off-road it will be on gnarly Hawaiian back roads.
For 30+ years I have always used BFG A/Ts on my trucks, but got a bad set on the last round so I sent them back and got Nitto Ridge grapplers.
I can worry about tires after I figure what size wheels to go with.
Any suggestions?

Thanks

Your talking 16" wheels. So I assuming it is an 03-05. 31mm was the offset of the OEM wheels. You can likely move about 5mm either way but will still likely have some rubbing with the front depending on the size tire you choose.

Hey Ghost........Yes 16" wheels ,2003. I know you can't have wheels stick out, or the back door won't slide open. I don't want wheels that do that. As far as hight, I would like to go 31". I plan on doing some trimming.

Thanks

I've got 245/75/16 mounted on OEM aluminum wheels. Required some trimming of the front bumper and wheel well when first installed. I recently installed 1.25" spacers had to trim the bumper and hammer out the front wheel wells again. Rear tire is about 3/16" from the bare cargo slider when fully open.

While mine is not an AWD. I have 295/50-R15 on a 15x10 0 offset wheel on the rear. My slider touches only because the bottom roller is bad allowing the bottom of the door to slip in

Not on the 03-05. You need to stick with the 31mm offset. a 26mm offset will give you the same as the 0 offset wheels that I am running.

http://www.rimsntires.com/specspro.jsp

245/75-16 on your stock wheels will give you a 30.5" tire

Suspension clearance: 15 mm (0.6'') closer to suspension/brakes components.
Fenders clearance: Will stick out 15 mm (0.6'') farther.
Wheel well clearance: Will fill out the wheel well by extra 23 mm. Make sure that you have enough room under the fender.

There is a web site that can help you figure out if the new tires might fit.
Just put in the original sized tires.
Then in the next box to the right place your new tire size and then see the differences.
That web site has alot of cool tire size info.
