You can find them on Roger Kraus Racing site.
On the left click on Race Tire Pricing, go down and click on the Goodyear tire file, then I think it's the top file that says "cobra tires", click on that and then it's like the third page. I just checked because I also want the widest front tire possible, yet keeping the diameter closest to 27 diameters as possible. As I'm sure your aware a 28 will not work on the fronts. Roger wants a bit over $400 per tire and the diameter i forget exactly but it's around 26.5 and yes that tire will work on the front. The only issue I see is that if your running a 7.5 front rim they recommend a min of an 8 inch. I know a lot of 275 tires out there say you can use a 7.5. I don't know what make you have but mine is a Superformance and mine is 7.5.
Just put Nitto 325/50-15 on the back and I love them!
