2022 ram1500 Laramie with 20’s upgraded to readylift 69-1935 3.5” lift and trx rims 325/65/18’s

[jsullivanii]

Recently bought readylift 3.5” lift for 2022 ram 1500 Laramie. Subsequently bought 2022 trx tires and rim, 325/65/18 and saw a couple posts that no spacers needed. Called readylift today and rep suggested they don’t advise tires greater than 11.5” and this is new tire is 12.5”. I had bought a 1/2” spacer but hearing from the rep at readylift it would need a 1.5” spacer. Wasn’t looking for that look to be sticking out that far.

Has anyone done this modification before or can help to confirm the calculation before I spend $$ at garage to have them put on and off? The rep suggested the tire would rub on the readylift bracket, I was assuming It would be on plastic molding etc.

appreciate any input/insight.

I'm running the 3.5inch sst kit with wicked wheels, 20x9 0 offset, and 35x12.50x20 tires if that helps with no problems. All depends on the offset of those wheels. Anything positive offset will possibly rub on the upper control arm. I know because at first I put the 12.50 wide tires on the stock 20x9 wheels and could barely get a piece of paper in between the tire and the uca. With the 0 offset wheels I get a good inch of clearance now. Hope this helps

Really appreciate it. I’ll check it out

Just checked, my stock 275/55/20's have 19mm offset and the 2022 325/18/65 TRX appears to have the same 19mm offset. In looking at other posts, I see comments from 1/2" to 1.5" spacer required. I tried the wheel-size.com website and not understanding how to input the lift to calculate the analysis.

With the positve 19 offset on 12.50 wide tires they are almost touching the upper control arms because I tried it. I did run it like that for almost 500 miles until my wheels came in. A 1/2 spacer would be fine with 12.50 wide tires but you'll have to ask whats the smallest spacer you can run without having to trim down your stock studs. I'm getting ready to put a 6 inch lift on mine and trying to figure out now what upper control arms to buy to match up with the backspacing on my wheels. All this figuring **** out makes my head hurt.

I get it, higher level math. Did you try the comparison at https://www.wheel-size.com/calc/?wh...18X12.5ET19&fcl=50mm&wcl=30mm&scl=50mm&sr=0mm. it shows a visual, i just cant figure it out!
