Need some help on wheels and tires

So, I have an 82 itasca sundancer. Been on the rebuild for the past 2 months and almost done, now comes the challenge of tires. It has 16.5 x 6.00 rims with LT 8.00 R 16.5 D tires and sits on a G30 chassis with rear dually. I could just buy the firestone LT tires that are offered but with such a limit I don't want to. I want to just slap new wheels on that offer a more selection of tires. So, anyone please guide me in the right direction. Thanks, Matt

The current steel wheels on it will have a small stamped model number (probably accuride). If you can find the number it should give you the specs, bolt pattern, hub size, offset, etc. you can then look up a 16 or 17" version, new or used.

I thought I answered this.....
My good friend, (another Matt) has a GMC and had a similar problem. Aftermarket wheels are available both in steel and alloy. The steel are likely to be so expensive that the alloy will only be a small additional cost.

I went crazy getting the wheels straight on the Cayo.

Not my first choice but since it is a G30 chassis there should be lots of used wheels around to fit it. Even the wheels from a Chevy or GMC pickup may work. Make sure they have the area where the lug nuts tighten against the wheel for the same nuts you have, correct offset, and not bent or damaged.

If you go with the alloys you will not have to deal with the one issue between brands of stock steel wheels, the diameter of the center hole. Since you're going to replace tires and wheels I would recommend at looking at late model take offs and seventeens. A take off is a new tire and wheel that was replaced by a custom tire and wheel by the dealer. Besides getting new factory tires and wheels there is the fact that manufacturers get the best tires. Your tires are rated and contrary to what they tell you at the tire store, the very best ones go to manufacturers. They buy the most tires and they don't want a bad tire ruining a sale.

I suspect sixteens are going the way of your sixteen dot fives. Seventeens are the size of the future and you will find more selection choices in the future purchases.

This means your odometer is going to be off. Your navigation device will help you work around that. I don't think an 82 has the computer that can be altered by the tech based upon tire size to correct the odometer. i use a Garmin and it shows my stock odometer is ten percent off, not an issue because I use the Garmin anyways.

Those old tires he has should be fairly tall and the speedo may not be affected much. My '88 has LT235/85R16s on it now and at 60 mph on the speedo I am actually going 63 mph. If his is too far off the gear in the trans is a cheap fix, or an adapter on the speedo gear shaft to the cable will work to correct it.
A check on a tire manufacturers website should have the tire heights and most even have a chart or program to tell you the effect changing tire sizes will have.
