Can the 5.3L with 3.23 10spd support 35inch wheels without re-gearing?

[shouldveGotDiesel]

Hey all, new to the forum! I've searched this topic around. I see a lot of stuff regarding the 6.2L but not the 5.3 with the 10speed. I've got a 2020 TB with the 5.3L and 10spd trans and I'm curious about 35 inch tires. I'm aware of clearance issues I would have to resolve, that's not what I'm worried about here

 

Couple of questions I couldn't find answers to in search:

 

1) Can the 10spd with the 3.23 ratio support 35 inch tires or is that pushing it? If I go on to tiresize.com, the charts there are already telling me the 3.23 is not optimal for the 33in tires that come stock with the TB. 35s obviously worse

2) Does the 5.3L have the torque or will I need to do some perf mods?

3) Will my top gears be essentially useless or will I be lugging at highway speeds in top gear and creating extra wear

 

I've seen on IG and on the forum people have the 10spd with 35s but its typically with the 6.2 and I never see anyone talk about re-gearing or problems with wear and tear on the trans (lifetime issues)

I know this isn't the specific answer you're looking for but I have a 5.3 with 10 speed and 3.23 gear. I pull a 30 ft travel trailer with a loaded weight of 7,000 lbs. So, to answer part of your question, I don't believe you'll run into an issue of a lack of torque.
