05 Tundra Double Cab 20" rims

Hi all, I've owned my Tundra since 05. Its a X-SP. It came with 20" Enki rims. I'm growing tired & broke buying tires for my toy. I honestly don't remember the original size, the truck came with. But V-rated is just a waste of money. I'm looking for a tire for these rims that isn't directional and will give me more than 10,000 miles. Thank you all in advance

 

Original wheel size is 16" steel or 17" aluminum.

Thanks, but X-SP edition has 20" Enki wheels. I was trying to find out what would 2 sizes smaller would be instead of 295/45/20. I don't know how to read the tire chart. I believe it might be 265/55/20. If anyone knows please advise. 2 or even 3 sizes smaller. Thx

Thanks I seen this in my searches. I just can't figure out what 2 size smaller is. I'll just probably buy the same 295 45 20. Since no one remembers including myself what came on it, when I bought it brand new in 05. Lol I have 1 hope left. My friend at Toyota. He's the parts manager now. Thx for your help.

In what way do you want to go smaller? Width? Diameter? Both?

 

Here's my 20" enku x-sp rims. With 295 45 20
