2020 tundra crewmax sx tire rim size level kit bumper shim

I have some 20in by 10in rims and I am trying to put 33X12.5 tires on without a 'lift' kit.

I have an extended warranty, bumper to bumper, lifetime, and it will be voided except for leveling the front without modifying the suspension, according to the dealer from where I purchased it along with the added lifetime warranty purchased


This thread does not seem to discuss 33X12.5 in tires:

Here is the 1/2in bumper shim, but I do not know how much 'extra' clearance the provides in regard to tire and rim size choices:

I was going to use that bumper shim with this 1.75in leveling kit:

Do you all think that would provide enough clearance without modifying the suspension?

If not, do you think their 2.5in leveling kit would (but i am not sure if it voids the added extended warranty since it has 'Differential spacers maintain proper front CV axle angle'):

I am more inclined to use https://www.roughcountry.com/toyota-leveling-lift-kit-870c.html?find=2020-toyota-tundra-4wd-569060 as it provides 2.5in in the front and may accommodate the 33X12in tire on the 20" rim but I am worried the 'differential spacers' may be considering a modification that voids the warranty

any feedback and assistance appreciated as these concepts are beyond my understanding

 

Not sure where you purchased your truck, but i just bought a 2020 Crewmax Tundra Limited last Monday and the dealers that I had shopped all over Tennessee are selling new ones with the leveling kits, 4" kits and even up to a 6" kit with 20's or 22's already installed and the factory unlimited warranty still applies. These were on all trim levels, including a 1794! I asked A LOT of questions about it prior to my purchase, including if I installed the lift later. I was told that it was all good. You may want to ask a different dealership to verify.

Here is a link to one, keep in mind that this dealer has a hidden up charge of $12,000 for the modifications that they don't display on their web page https://www.toyotaofcoolsprings.com...yota-Tundra-Platinum+57L+V8-5TFAY5F10LX909992

 

Your dealer is full of it! The Magnuson-Moss act protects you from BS like this!
