Sorry for the long post. This has been a headache to try and find “factual” information on instead of “opinions”. I have a 2019 Silverado work truck V-6 , 6 speed, with 3:42 gearing. I have a stock suspension. The 2019 work truck comes with three tire options From factory. 1. 17" 255/­70R17 all-season, blackwall tires (my current tire) 2. 17" 265/­65R17 all-terrain, blackwall tires 3. 17" LT265/­70R17C all-terrain, blackwall tires However, ... the Silverado Custom (with the same 3:42 gearing) comes with the following tire opens. 1.20” 275/­60R20 all-season, blackwall tires 2. 20”275/­60R20SL all-terrain, blackwall tires 3. 22” 275/­50R22SL all-season, blackwall tires My current truck has the 17” 255/70R17 all seasons. I love my truck, but I absolutely hate these tires/wheels. They look like baby wheels on a big truck. Way too much fender well free space. Looks like the truck missed “leg day“. My question is if I purchase the OEM wheels and tires for the custom, is there any issue with them fitting my work truck? As far as I know both trucks have the exact same suspension, body clearance, control arms, wheel well clearance, etc. I was looking at going with the 20”275/­60R20SL all-terrain, blackwall tires. The only changes that I could forsee that would happen are the following... 1. An increase in wheel diameter of current 31.1” increasing to 33”. 2.a width increase from 10” to 10.8” 3. A sidewall decrease from 7” to 6.5” 4. A revs/mile decrease from 650 to 612 (affecting speedometer speed by .058%) 5. A new effective gear ratio of 3.22:1 6. A change in tire run pressure from 35psi to 32psi. (Annoyingly setting of my TPMS “low pressure” alarm ) several questions.... 1.will these custom tires fit my work truck? I can’t Find any reason that they won’t 2. Will the dealer reprogram my speedometer for the percentage difference, and replacard/reprogram my ECM with the new psi setting to 32psi. (Not sure if they will since the Vin number of my truck does not include these tire size as “options“.) I really don’t want my low pressure alarm going off 24/7. 3. Will I noticed the change in new affective gear ratio from 3.42, to 3.22? (I’m assuming I won’t since it is the exact same gearing/tire size as the custom. Man, there sure is a lot to changing a tire size. Almost doesn’t even seem worth the trouble. Am I going down a bad rabbit hole? Just an FYI, I am not interested in lift kits, aftermarket speedometer programmers, etc. . Would like to stick OEM as much as possible.

2014 Silverado LTZ crew cab 4x4 I recently put my rear air ride suspension on and waiting for my 3in motofab leveling kit to come in. With the 3in kit up front what tire size can I go to now? Will I need a bigger rim? Do you have any pictures of stock rim with bigger/beefier tires? Do you have any pictures of larger rims with bigger ties? Currently running stock rim with gy 275/55r20 all terrains

Hey all, so my plans originally for a 4" lift with 35s has taken turn and as of right now I will be going with a RCX 7" lift (I decided on RCX because I can keep my turn radius as close to stock as possible and after driving in a few trucks on dealer lots that were on 6" lifts and 35s with kits that restricted the turn radius, I can't deal with that wide of turns all the time. I have talked to a few wheel/tire websites that do deals when you order a wheel and tire package. But haven't been told by any what kind of issues I could run into with a 12.5" wide tire on a 12" wide rim. I can't imagine that this could end well. But like I've said plenty of times in the past, this is my first truck and first lift/rim/tire change experience. Ive changed tires on my old Yukon before by just to something that was the same as stock so changing everything is new. If anyone could give me any insight on what kind of issues I could expect by running a 35x12.5x20 tire on a 20x12 rim, it would be much appreciated. Even better if any one has anything similar. Also, could I run a 10" rim and possibly get the tires to stick out as far? I am wanting to get the tires to stick out 2" past the stock fenders so that I can put on some 2" extension fender flares from Southern Comfort Automotive and the tires will line up, or at least com extremely close to lining up, with the fender flares I don't plan on getting my lift until the summer, probably around the middle of summer to be exact. Thanks in advance - Mike
