i got a 2" level with add a leaf. was going to do 34" or 33" tire.after reading everything on gears,i have 3.31, now im afraid to go with the 34s so now leaning toward 33s.but now im wondering if a 275 65 18 duratrac would look good with this level.its the same as my stock tire size so wouldnt lose as much because of gearing.my truck has six speed tranny with 5.4L engine.will the 33s dog it that much to make a big difference? will i see that much of performance lose between the 32s to the 33s?

 

This is mine with a 2" AS kit and a 3" block in back and 275/70/18


This is with stock tires 275/65/18


I lost just over 2mpg

 

did you not ask the same question five threads down?

this is a picture of my truck. 2 inch level on 275/70/18 so about a 33.5 imo it looks great with the level. as far as gearing i wouldnt be concerned until you get in the 35 range. if you need more pictures let me know

 

thanks guys.yes i did ask about the 295s. im so confused on what to do. took me six months and many calls and reading a thousand post on what level to do.now i got the level kit in the garage and not sure which tire to get. driving me nuts reading all the info.on different sizes,gears,white letters in white letters out etc.i just dont want to make a mistake with tire size etc. sometime i think i research things to no end.al least thats what my wife says.

 

both trucks look great.jdeacon, are those 33s? they look big.

 

If the original are 275/70R18 and you go with 275/65R18, you will have a speedometer reading of 6.5% too fast at 60mph.

 

the originals are 275/65/18. probably going up one size to 275/70/18s

 

also what doe anyone think of the 295/65/18 duratracs as compared to the 275/70/18s? they are a 33" tire only wider.

 

my tires are a 275/70-18 which is about a 33.5x11x18 they fill out the wheel well slightly better than my old 33s imo and only being 11 inches wide they dont really throw anything on the side of the truck. let me know if you have any more questions! i may even have some pics of my 33s on the truck somewhere...

 

k so for reference, here is a 33x12.5x18 on my same truck with my same 2 inch level, compared to my earlier pic which is now on 275/70-18

 

thanks guys.making a trip to florida in a week and when i get back the level is going on and ive decided on 275 70 18 trail grapplers.thanks for all the help, i will post some pics in a couple weeks.

 

I have the same stock setup with 2" AS and 3" rear block kit. Debating on what to do with tires and rims. I noticed you have different rims. What kind you went with? How is ride quality after tire and rim change?

 

went with incubus brawn 18x8.5 wanted 9 wide but they work I guess, ride is stock feeling, check my sig.

 

Greetings to all and Happy New year:
This is my first post as I just signed up. I don't mean to cut in but you all seem to know the answer to the question I am about to ask.

I have a 2010 stx 4x2 with 265/60/18 tires and was given a set of 235/75/17 tires and wheels and want to put them on for the winter. So far from what I have read , it is OK.. HELP, I am not sure.

Thanks

 

Going from stock 275/65/18 to 275/70/18 you will be fine no gearing needed. Speedo didn't really change if any maybe 1 mph difference but using gps and my speedo were pretty much the same.
