I run Michelin passenger car tires. Size I think is p215/75 r15. Stock wheels, stock suspension. The tires don't rub any suspension components, but at full lock they rub the inside edge of the front mud flaps. Trim the flaps slightly or remove them to fix this.

I really like the Cooper Discoverer line of tires. You could run the ATR's in 235/70R15. They are a little less than 1" wider than stock and just a little taller but not enough to rub on anything. They are about 28" tall.

If you are towing or hauling heavy loads the LT rated tires will perform better for you.

Dean,
Any speedo problems with the tires being taller??.Or is it so small that I doesn't matter??.As I said,I am looking for new tires for the LT.

Hey-what's with the not stro less for long??.

Generally the manufacturers have the speedo read a little high so when you step up in diameter a little, the speedo actually reads correct.

For me, I have an 2001 AWD Safari and find it "lugs" with its existing 3.42 axle gearing. Thus, I installed P215/70-R15 rubber on its factory rims. Rubber is slightly smaller diameter and lighter weight rubber then its factory recommended p215/75 r15 rubber. Based on research, the 70 series is 3.1% smaller diameter then p215/75 r15 rubber. Which means my van's speedo reads 60 mph but actual ground speed is 57.5 mph. A little less "lugging" (due to engine's now higher RPM) and thus, gain in 1-2 mpg more (as per my van's DIC).

I went with "P" rating on our AWD because we do 95% passenger traveling and some light weight utility trailer towing. My previous '95 RWD van had LT tires. I found the LT tires felt a little rougher on the straight roads but they "hugged" the sharp corners much better. With LT tires, I find much less tire / body roll on those sharp fast corners.

For my current AWD, I lifted its front 1.5" via torsion bar adjustments. Added +1 leaf and installed Timbren SES units in its rear (with 1.5" spacer under its Timbren). Thus, lifting its rear approx 2.0" higher. Overall, its 70 Series tires and 1.5" lift, its "stance" looks great. Much better then factory stance. And my van drives much better as well. With tighter suspension, it now "hugs" the roads instead of "mushing" down the road.

If I had a RWD van today (that didn't "lug" under average load) that would be used for mostly passenger hauling / country side touring, I'd probably go with LT215/75-R15 tires. Or, go with LT215/70-R15 for slightly `more space `around its wheel wells. Probably go with "all season" Michelin brand. Also install High quality shocks (all tires) and install Timbren SES units on the rear would bring its suspension to "where it should be". Especially if the the van is loaded with normal passengers and/or average internal cargo. To me, the factory suspension and "P" tires have way too much "mush" feeling.

Hope this helps in your research....

great way to put it, thats the problem I was searching to explain, its kinda like driving a big sponge thats the only way I could explain it,

thanks that was a huge help. (especially with me trying to tell my wife I need new tires)

[CaptSquid]

Go with any good LT tire the same size as currently on your vehicle. Passenger car tires just don't have enough oomph for these vans.

[kings-x59]

I agree with the Captain. The sidewalls of passenger car tires are a bit on the soft side. I'm running Kumohs, they're good tires but the sidewall flex disipates my sway bar and shock performance some. Next set will be stiffer.

Okeman,

As a suggestion, only replace existing tires if "they are worn out", they are "over 6 years old", or you must change your existing tires anyway. Replacing one's tires `for the sake of replacing one's tires` seems expensive.

For more details about tires being more then 6 years old (based on their date stamp), surf: http://abcnews.go.com/Video/playerIndex?id=4826897

Note: When you obtain new tires (like: LT215/70-R15 on factory size rims to obtain slightly `more space `around its wheel wells) remember to check their Creation Date stamp on each sidewall rubber as well.

Hope this (and ABC News video) helps as well...

I saw that when it was new, as far as replacing them goes, I hate the ride and the feel of them so there gunna go regardless, I just dont feel like im driving on a safe tire there a uniroyal tire but they seem like junk under the van, thanks for the tip.

I too am looking for tires for the LT.Don't over look Lifted's suggestion for cooper tires.They don't have to cost alot to be good.

i am running general's a/t and it is real nice priced real fair

I have 3.42 ratios in my 2003 AWD Astro. The 2003 to 2005 have 16 inch rims and rear disc brakes which is nice.
I am running LT225/70-16 BFG TA KO's very stiff and handle well but they are heavy. About 3 pounds more per tire and mileage is bad. about 13 mpg city and 15 highway. Also, the van is lugging a bit from start up on steep dirt roads.

I am planning to install the 2 inch Overland lift kit which I purchased this summer. with the beefy tires the van should be great in dirt and snow with the lift.

I would like 3.73 or 4.10's but too much $ with front and rear pumpkins (aka differentials)

I wish GM would put out a new Astro with hybrid drive or diesel and just stretch the front end a little to allow and better steering system with better turning circle.

I have P215 75 R 15 on my Safari. The ride is a little soft, and with the load I've got in it, I will be stepping up to LT tires in the spring. I have a set of Michelin P 215 65 R 15 M+S on my Astro van, with less than a hundred miles on them, I put two on the rear of Safari last week when I had a flat and didn't care for the ride, like riding on rocks in the rear...

might be fine in the snow, but sucked on dry pavement.

I'll most likely sell the Michelins when I find something I like for the Safari
