This isn't an accusation, but a principle to live by that my Dad taught me as a teenager. "Either do it right, or don't do it all." 35" tires need lower gears for the truck to function properly. 4.56s will put you back to basically stock gearing. I learned this the hard way on my '89. I was only running 33s. I put the tires on and then did cam, headers, intake.....trying to get my power back. Nothing fixed the problem until I put in 4.10 gears. There's no replacement for proper gearing.
