Man, what a difference in price. Is this the tire:
Carlisle Tire & Wheel Company
If so then there is a (supposed) 1.2 inch difference in the advertised diameter. The 25" Goodyears show up as 24.0" diameter on Goodyears site:
Goodyear ATV - All Terrain Vehicle Tires: On The Wings Of Goodyear: Find the Right Tire
The Strykers are showing 25.2". It will be interesting to see how they compare to each other in the real world when you measure them.
Couple of questions:
How do you think they will ride compared to the Goodyears?
Also, what kind of sidewall problems were you having with the Goodyears?
