STI Tire & Wheel now offers a smart choice to cross-country sport quad riders and racers with the release of the all-new Tech 4 XC. The STI Tech 4 XC brings high performance to the market at a surprisingly affordable price.

The Tech 4 XC is specifically designed for serious trail riding and racing. It provides an extra level of trail durability with a 6-ply rating and utilizes a high-tech rubber compound that delivers exceptional hook-up on hardpack surfaces, in a unique tread pattern that pulls strongly through soft loam - a winning combination. Lightweight construction reduces unsprung weight and rotational mass for unmatched acceleration and ride. The Tech 4 XC's carcass is designed to reduce bounce and enhance high-speed control and cornering confidence.

Tire Specifications:

  • Tire diameter: 19.7".
  • Tire width: 11".
  • Rim diameter: 9".
  • Ply rating: 6.
  • Thread depth: 1/2".
  • Maximum PSI: 7.

Great Tires

I bought these at the last minute while my quad was in for service. That way they would install them while working on other items. I was impressed with the price and fast delivery. They have a great tread design and should work great for the type of riding I do. Mostly trails and back country, I can't wait to try them.

15 Ds450 Xc

Tires are good, lots of grip. My 2nd time ordering the tech 4 Xc. Had the rears on a kfx450R that I had and liked them. So I went with the tech 4 Xc on all 4 corners of my Can Am Ds450 Xc. 6 ply, Xc tread, good rubber compound.. Did I mention the price is right on point. I'm a repeat buyer of these. BRAPPPP

DISSAPOINTED

I bought a set of rear 20 inch sti xc. I blew a side wall out my first ride. I emailed the company and got a replacement rear, which I was super happy about. I was surprised they stood behind their product so well. I ran the tires for a few months this past summer and same problem happed with the other tire. So I bailed on them. could be a great tire they wear super well they looked new when I took them off. The side walls are absolute garbage. no more chances taken. Cannot be a true 6 ply tire. or maybe I ride too hard I don't know, never had this problem with other brands. Hope STI can get them right and fix for those weak sidewalls.

Great Affordable Tires

Bought these to replace my stock tires on my YFZ450. What a difference these made on my ride! These grip the loose dirt/gravel very well. Not to mention they are pretty affordable. Would definitely buy again.

Scared to ride on them

I had my new tires mounted today and when I went to put them back on the quad I pressed on the sidewall. Felt and heard a cracking noise. I the hope the things don't blow out on me the first ride! And they sure don't feel like a 6 ply tire.

Happy with Purchase

Can't beat for the price. I ride trails and find myself in some thick stuff and these handle fine. Purchasing second set of rears and still on my first set or fronts so they wear well too

Best tires ive ever bought!!

Bought these tires for my 02 660 raptor and they look sick. I ordered them and 3 days later I had them installed on my quad. Great fast shipping and you cant beat the quality of this tire. They have thick tread and they grip like crazy. I would recommend this tire to anyone who wants a rad tire that is high quality for a great price.

GREAT TIRES

I got these tires for the back of my KFX 450R. I ride on lots of rocks and climb coal hills, they work great. The traction is great. I was on about 5 rides and they show on signs of wear at all. I will buy these tires when my sons quad needs rear tires.

Do you have a size that would fit on my 2013 yfz stock wheels, 20x10-9?

ATV wheels and tires are made in multiple sizes for different machines.
Wheels are listed as “Diameter X Width”
Tires are listed as “Height X Width X Wheel Diameter”

You will have to make sure the first number in the wheel size and the last number in the tire size are the same so that the tires can mount on your wheels. Also, feel free to give us a call at 888-676-8853 and we would be happy to help you out with your order.

Would these tires be good for mountian trails? and some snow?
Expert MotoSport Staff

The STI Tech-4 XC will hook up great on mountain trails, from Hard pack to soft loam. In the snow they might pack up with this tread pattern. I would search the forums for people who have been running them in snow.

If you are currently running 20x10-9 tires, you shouldn't have an issue with 20x11-9 tires.

Yes, the 20x11-9 tires would fit the same 9 inch rim that your 20x10-9 tire fits on. The tire is just an inch wider.

Will a 9 inch tyre fit a 8 inch rim?
I know I can fit 11 inch wide tyres on the 8 inch rim but will a 9 inch diameter tyre fit on 8 inch diameter rim Rear stock tyre = 19x8x8 New tyres = 20x11x9

1 year 9 months ago Location: Portland, OR, USA

No. This tire would need to be mounted on a 9 inch rim.

Is this for just the back tyres or the front?
MotoSport Staff Expert
1 year 9 months ago Location: Portland, OR, USA
MotoSportRyanT
The STI Tech-4 XC 20x11-9 would be a rear tire. The matching front tire size would be 21x7x10.

I got the fronts after I bought the rears, they both work great. I got the 22 inch for the front of my KFX450, it helped get rid of the high speed twitchy feeling it had with the stock tires. The tread is very tall on the fronts which helps on soft muddy dirt. I would buy again.

Wich tires good for ice, snow and winter for a 110 cc ?
1 year 9 months ago Location: Tower City, PA 17980, USA
TROY84
These are a heavier tire with there 6 ply rating. They work great on a bigger quad. With your small 110cc quad I would look for a lighter weight tire. These will take more power to turn them because of the weight.
