## Questions & Answers

**Q: Do these tires have the white lettering like the photos show?**
A: Hello,
According to the manufacturer part number, these tires do come with the white lettering on the sidewall. Hope this helps!
Thank you,
Tires-easy.com

**Q: Are they blackwall or white outlined?**
A: Hello,

These specific tires actually come with a black sidewall, so it does not have the raised white lettering. This information is located on the description of the tire, (for future references). BSW is for Black Sidewall, WSW for White Sidewall, and WL for White Lettering. 

Hope this helps!

Thank you

**Q: Does the 285 65 r20 come with raised white letters? i noticed it says blk next to them.**
A: Hi! You can select the 285/65R20 size with either a black sidewall or raised white lettering. Just select the option you'd prefer in the drop down! Thank you!

**Q: Anyone know how well these do in snow? My 2010 ram sucks with the current tires im looking for a good winter tire**
A: I have a 2014 Ram 2500 with these tires. This is my first winter driving with these tires and for the first time I am able to drive good in the snow without being in 4wd. Of course in deeper snow I drive in 4wd, but can go regular speed with no issues.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great tires
*by A***R on September 7, 2025*

I’ve had these tires on my 2500 service truck for a few years, they ride smooth, they’re not loud, and they haven’t worn down much at all. As for balancing, I have double beadlock wheels with rubber inserts so I use balancing beads (also purchased on Amazon) and there’s a negligible shimmy every so often. Also, the shipper, Autoplicity, has fantastic customer service.

### ⭐⭐⭐⭐⭐ Worth the money.
*by J***E on January 27, 2025*

Second set of these tires I’ve had on 2 different vehicles. Low road noise as long as you have a good alignment and rotate on schedule. They last longer than most A/T truck tires. Good traction on all surfaces and they look good. Just wish they put white lettering on the 20” tires.

### ⭐⭐⭐⭐⭐ Good Product
*by R***H on September 15, 2025*

Great tiers. Duarable. Rides good in rain. No vibration. Good traction on off road. Would buy again.
