What size should I go with!

Hi All,
I don't have much knowledge about the tires especially when leveling kits and suspension is involved, I browsed many threads and articles, but couldn't wrap my head around it.

I own a 2019 Tundra Platinum running 295/55R20 which I will need to replace. I was looking for Discoverer AT3 XTL same size as I hear its more comfortable but yet looks aggressive enough for me, but unfortunately I cant find this size!

So changing the size may require some modifications which I dont understand and this is where I will need your help, if I go with the 305/55R20
- Will that require any modifications? what? ( I was thinking of lifting and leveling the car but hasn't decided on how high should I go and what factors should I consider)
- Will that add more stress on the car? (with the modification)
- Would you advice I go with a different

I use mainly the car in city and on highways!

 

It’s a truck.

305/55R20 is 33.2”x12”. The height will easily fit under a stock truck, but the width is pushing it for 8” stock wheels. I’ve always been told not to go 4” wider tires than the wheels. If you do, they might also rub your UCA.

 

Thank you timsp8, in this case will I need to do a cut, or is there something I can do?

 

Take a pic inside your wheel well to see how close your current tire is to the UCA. Then add ⅜”- ½” towards the UCA for the new size tire. If it rubs or is too close, back to the drawing board.

 

Honestly, if you're not understanding the mod or it's need, don't do it. Instead of changing your tire size and going down a rabbit hole half cocked on a mod that you say you don't understand, pick a tire that is made in the size you already have on it. If you're dead set on that tire and it requires a size change then you need to educate yourself through research. There's enough info and threads on tires, sizes, suspension, lifts, etc. to fill the the Library of Congress. Before you mod, you need to understand. You don't have to be an expert, but you're taking responsibility for changing your vehicle from the way it was engineered, so you need to have some understanding of what you are getting into.


If you answer "no" to any of these 3 questions I would advise you to keep researching before changing your tire size.

1. Do you know what offset is?
2. Do you know that changing your tire size will change your fuel economy?
3. Do you know that changing your tire size will make your speedometer, odometer, and fuel calculations on the dash all be inaccurate?

 

Thank you guys!

@GODZILLA , yes I know the answers but I do agree with everything you said!

@PermaFrostTRD, that makes perfect sense, how come I didn't think if that!
