I have an 03 Denali with the goodyear 17's. 25,000 miles the tires are pretty much used up, and I will need to replace them soon.

any suggestions beside the OE goodyears ??
I want something QUIET. I do ALOT of long high-way trips and hate road noise.

I also see a fair amount of snow, and I noted the OE goodyears were not the best, and because the Denali has an open diff, snow traction was poor.

any suggestions??

I've got an '02 Denali with the OEM Michelin Cross Terrain 17". With 32,000 miles, they've still got more than 50% available tread! Tires are extremely quiet on-road and give decent snow traction. Not cheap as replacements, but well worth it. BTW- one on my sons has Goodyear Wrangler HP's on an '02 Durango R/T and they are wearing quickly -- maybe his driving habits!?

The Blur,
I went through same research as our 04 was delivered with the OEM high mileage tires. I see same conditions you do. 75% road miles and 25% snow. I switched my tires to the Bridgestone Dueler A/T's. They are incredibly quiet and work great in snow and rain. I am putting the same tire on my Dually Monday based on what I have seen with the Denali. The wear seems to be OK. We have about 13K miles now. I rotate them every 7K miles.

any other comments on 17" tires for the denali?
I need some real soon..

I have a 2001 Denali in Canada and currently have 120,000 Kms on my tires with life still on them. I do a combo of City/Hwy/Cottage driving. I love Michelins, always have, like them best in wet weather. Take care!
