Help please

Hey all,
So I went with the VMS wheels 17x10 in the rear and 18x5 in the front. Put MT 305/45/17 in the rear and MT sportsman 28x6 in the front. Once I mounted them I got the dreaded Christmas tree of code. All of my research before hand led me to believe these two tires and wheel sizes would work together. I have read on a lot of pot that if the wheels and tires are a % difference that this would occur. How do I determine that? After reading all the post on here about it I’m guessing that’s my problem but don’t want to spend more money on a whim either.
Thanks

I have the same size wheels. 18x5 and 17x10. My fronts are 28 inch tall, rear tires are same as yours. and I didn't get any codes.

You are well under the 2-3% size difference, I would check if you have a unplugged/broken or bad speed sensor in all 4 hubs.

Thanks,
I did do a lot of work in the rear before the new wheels and tires but the codes didn’t pop until I took the 20,s off and put these wheels and tires on. I will check the sensors while I keep searching for answers

Yeah its not the wheel/tire setup, you are like 0.7% on tire difference. I ran my 15" beadlock and 18" fronts at 1.4% difference and I had zero issues on my 1LE.
