should i do 20s all around or 20's up front and 22'S in the back and if so how big can i go in the rear. I am also going to bag the truck. any info helps.

 

Me personally.I would go with 20's all the way around with 255/35 20 if you are gonna bag it.I like the same size tires all around if ytou are gonna drive it everyday that way you can still rotate them the way you should.Thats my personal opinion.

20s out back and 18s up front

 

im not doing 18's too small and it is not going to be a daily driver. so on that note.

 

I bought this but its expensive, I figure I will work on enough cars and trucks to make it worth while.

You pretty much have to really do your home work with a wheel tire selection on bags.
I bagged my first truck and ran tires that were a little bit too tall creating the bags to not be completely deflated when truck sat down on the wheels. You can't plan ahead unless you have all the right measurements. bag placement c- notch depth, pinion angles all depend on tire height and rim size.

If your buying a bolt on airide kit or something similair they should no exactly what tires to run in 20" sizes so you can get the maximun drop and lift out of your bags.

Any truckin mag lists bagged trucks and there tire sizes so that might help you too.
I would think a 20x8 w a 5.5 backspace on a 27 tall tire should be good for a bagged silverado. If you wanted 22 in the back all you would have to do is get the same height tire as the 20's or a little taller. But your selections are limited on matching sets and it will prolly cost you for a euro type tire.

I had 20x9.5 rims front and rear with a 5.75 backspace and 275/45-20 gygtII. My truck is only a 2-4 but if I bagged it I would need to step the rims in to 6" or 6.25 Backspace or downsize to 8" up front. You could run 22x10 with a 295 in the rear and tuck if the the back spacing was right ie custom wheels. If your upgrading to 4-link that will even give you more room in the back.

Inro custom wheels is real helpful and will make custom backspacing. I'm going with the smaller 18"s all the way around because the 20's I had were so damn heavy and I need evry advantage to go faster.

 

yo jj where are you at right now. i didnt think you would have a computer.

That is a guy from intro wheels.... he is running 20/8.5 and 20/10 bagged with 245s up front and 295s out back.

I'd say stick with 20s in the back. Then again 22s would look pretty damn good....

 

22's on all four corners! I really wish now that I'd have saved up and got the 22's when I bought my rims.

Just for the record...I have Boyd Coddington Spyders, 20X8.5 with 6.0" backspacing all the way around on 255/35/20s and they appear to be able to tuck with no problems.
