Just bought truck new in September, I have been through car washes, rainy weather and never had a leak. The first wet snow we got about a two weeks ago and got in truck and saw this, it was leaking so bad leaking it was running all the way down pillar and onto emergency break pedal! I made an appointment at dealer, they said it was the satellite antenna leaking, and that a lot of new trucks are doing it. Had to order a new antenna for it as its all one piece, had it installed yesterday, will see if it fixed the problem! I also told them i wanted i new head liner and they said was on back order at GM since they are replacing so many of them! Just thought i would give a heads up (literally) to watch for this problem!

Thanks for the pics! Love that look, awesome looking truck, that's exactly what i am going for! Never really thought about 305's, can't believe they don't rub, i am glad! I love it, and also like the bfg's. Thanks for the info! This is the truck that started my love of this look. It is 295-55-20 on 20 x 9 0 offset, he said he has no rub!

So after hours of going through all the wheel and tire size posts i am still needing some help, and more confused than ever! I know topic has been beat to death, i just still don't find a definite answer, and would like some input before i pull the trigger on $1,300-$1,600 in tires! So here's what i got, I have a 2016 1500 Denali with a 2.5" front suspension maxx leveling kit with the rear 1.5" blocks with the black stamped steel uca''s and factory mud flaps. Living in northern N.Y. i wanted something more aggressive for winter then the stock Goodyear tire that were 275-55-20 which is 31.4" x 10.8". Having great success with the Cooper ATW's before on other trucks i wanted these tires, but to get more tread depth and a 10 ply tire for towing enclosed trailer i had to go with a different size. The closest to stock i could get was a 265-60-20 which is 32.5" X 10.4", this equals 1.1" taller and 0.4" wider. Having seen guys on here running bigger tires that that on stock 20" wheels and said they had no rub i thought i would be fine with this size. Mine rub the uca's pretty good at full lock and had to zip tie the liners back. Some guys on here say they have no rub with 285-75-18 which are 34.8" X 11.2" on sierras with same leveling kit with no rub on uca's? I believe the wheels are same offset which is +27MM, about 1". With all that said, i can stand the rubbing since it only at full lock, just confused why a tire that is .4" narrower is rubbing with uca's, the stock tires never did, i get that they are taller and that was solved with the zip tying the liner back. And the real hurdle that i need info on is that i have a new set of RBP 94R 20X9 wheels with 0 offset to go on in spring which i bought online from a off road truck shop in California who said that they run that wheel combo all the time on leveled GMC 1500"s with 295-55-20 and 295-60-20 Nittos with no rub at all. The wheel will be pushed about 1" out due to offset but the 295-60-20 is about 1.2" wider and 1.4" taller and 295-55-20 is about 1" wider than i got now, so if the offset cancels out the 1" i will still be rubbing just the same as i am now! I was looking also at 285-65-20 on leveled 1500"s those are taller yet, but a little narrower, but i would believe those would not fit at all since they are 34.5" high! All these numbers make my head spin!! I guess it boils down to how much rub i can live with. Any info on any of your wheel tire combo that is close to this would help me! Thanks
