I search for hours on the TrailVoy forum for a definitive answer about tire sizes and suggestion's from fellow members.
I never came up with a perfect answer for my stock set up, but with enough piecing together of information, I decided to go with Bridgestone(BS) truck tires verses car like tires. I almost chose to go with the GY Triple tread. I couldn't find enough on these tires and also thought the tread looked to wimpy on a truck/suv.
I bought my tires at www.tirerack.com since their warehouse is 4 miles from my driveway. I checked the comments on tires there as well and found that the GY's had only 1,000,000 driver reported miles and the BS's Revo had 41,000,000+ driver reported miles.
About the Trailblazer: 2004 EXT 4X4 V8 TNF, all stock, with >40,000 miles.
factory 17" wheels. The origanal tires were very near the wear bars and only one had worn badly on the inside.
About the tires selected. I upsized from OEM 245-65/17 to 265-65/17
Bridgestone Dueler A/T Revo. The tread width is only very slightly wider then the 245's that were on there.
My review.
I think the tires make a little more noise and the gas mileage drop about 2 miles a gallon according to the DIC. I will update the gas milage after I run a tank and fill up. My wife thinks they make less noise.
The TB drives much much better. Both myself and my wife think the ride feels taller, more solid and more powerful. Gone is the soft bouncy ride of the conti's.
The TB looks much bolder and more serious about being a 4X4. Pictures to follow.
Not sure if the trade off of gas milage is worth all the benifits, I'll have to wait till after I wipe this stupid grin off my face and take a serious look at the overall ride quality improvment and loss of a few MPG. More to follow after we put some miles on these tires.
