Bought a new (to me) 2011 egg after our 2004 was given to a friend in need.

Looking at getting winter wheels / tires and considering just buying 20" winter tires and upgrading to something bigger for the summer time. A local posting has a killer deal on 22" Cayenne rims + 295/30R22 tires. Other than the diameter difference, the concerning thing is that the tires have a load rating of 103. Looking at the forums it seems at least 106 is recommended, but thats what I used to have on my T1, which was apparently 800lbs heavier. Should I be concerned? It did come off a Cayenne which has a GVWR of the same as the Touareg (6173 lbs sourced from http://press.porsche.com/vehicles/11_press_kits/pdf/2011_Cayenne_Specifications.pdf and Used 2011 Volkswagen Touareg Features & Specs | Edmunds)

No towing is planned.

Can I safely stick w/ the 103's?

You'll need to check regulations in your country/state - some require specific manufacturer approval but others simply that the load rating is higher than half the maximum axle load.

Wide low profiles are not a good recipe even for proper winter tires.

103 load index is for cars, not SUVs. Some people buy car tires as they are cheaper. You're risking a blowout by not running proper tires for the vehicle, so IMO no - I don't believe 103 is safe to stay with.

The winter's would be on the 20's. These would be summer tires.

103 load index is 1874 lbs/tire, for a load capacity of almost 7500 lbs. Hardly "car" territory and still 1400lbs above the max loaded weight of the truck from my research.

Thanks, this seems like my path as I guess i'd be most concerned about liability.


Has anyone on the forums run these sorts of tires before with their T3?

FYI there is no XL rated 103 tire; hence its a car tire. The only 22" that rated to run on these vehicles are 285/35/22 106XL.

If you want to run 103s and risk a blowout, knock yourself out.

The specification calls for 106XL the XL part is critical, as is 106.

Look at the car manual. That is what insurance companies will refer to. 103 and insurance will be void. Your risk.

A 295/30/22 tire is NOT a 285/35/22 tire. If you're running 22s the right size to run is 285/35/22 and that size is only available in 106XL.

The manual, decals and every other bit of tire information for these vehicles is very clear on stating 106XL is required..most of us running 20" tires actually run a 110XL rating.

I suppose you can run out of spec tires in the same way you can run out of spec oil, typically with catastophic results.

So you asked "can I run a 103" the answer is "its out of spec". You can choose to take the info and do with it what you will.

Here are several more 103XL which surprises me. Whether you can get all or any of these in Canada, I know not.
This particular size (295/30/22) is commonly run on Camaros. Why its an XL rating I'm not sure, though the gen 5 Camaro is heavy.
