2010 tahoe/suburbans have 275/55r20 tires can a 285/55r20 be substituted without a problems.

i would like to use bf goodrich all terrain tires but they only come in the 285 size

How much bigger are they? Clearance at full turn would probably be the only issue. I jumped from the standard 245's (only size offered on
3/4 ton burbs.) to 265's. The duratracs rubbed at full turn but my new silent armor's dont.

what do you think of the silent armor tire. i like mine but they dont seem to have as precise steering as the duellers did. and it seems like i lost a mpg in fuel economy.

Did you get the Pro-Grade tires? The salesman at the goodyear store Told me to stay away from the non Pro-Grade silent armor's. I love them, man they are the quietest tire i have owned and i see my mpg's went up due to a non aggresive tread pattern.

i have the non pro grade version. the pro grade has a different tread pattern than the non pro grade? i thought it was a different rubber composition.

they are quiet for being an all terrain tire though.

I was told not to go with the Non pro grade because of their load rating and sidewall flex. I have the 3/4 ton. I could not run the tire Pressure for the non pro grade, my sensors would constantly go off. I had to go with the E range. you are correct about being a quiet tire with an all terrain pattern. Fourwheeler mag did a test of tires and gave the silent armor 5 star rating for snow and they were correct. only drawback on these tires are thet are PRICEY.

was there any issues with your alignment? are the tire composition harder on the pro grade? i have a 1500 series suburban.

LTL4life

I leveled my suburban by adjusting the Torsion bars 2 years ago so i needed an alignment. It has tracked perfectly straight since then so no alignment was needed. I contacted goodyear prior to purchasing. i saw several comments about sidewall failure and premature wear. i was told this was because of folks with HD and 3/4 ton as wellas owners that tow/carry heavy objects not using the Pro-Grade ones. I think with a 1500 Burb you would be fine.

how tight is the steering. does it tighten up with speed or get looser?

LTL4life

Kinda feels the same although it felt Tighter with the duratracs but i was running less pressure with the Duratracs and the agressive tread pattern probably made a difference.
