Lone Star's with Good Year Billboard Tires ?

[FUNFER2]

Sorry guy's. I do have 295/50's but was interested in the 60 series, to fill up more of the wheel well. Looks like the 295's don't come in the 60 anymore. A friend just notified me that he tried to get the Good Year Eagle II's in this size. their not making them now, don't know why, other than no sales. Anyway, I have apx. 3/4" between the tire and frame gusset. If I buy the Billboards, I'll have to stay with the width of 295's, no problem with that. I'll have to look at the chart Bruce posted and see what diameter in inches will fit and measure (twice) lol, what I have now. I still don't know what's up with my shocks (Aldan adjustable) and why I have so much dead space between the top of the tire & wheel well. If you stand back and look at the rear of the car, you can see that the left side of the fuel tank is lower than the right. The left shocks adjustable collar is all the way down, the right side is in the middle. I can't lower the rear of the car because of the left shock being all the way down now. This winter, I'll have to scale the car on all four corners, take the springs off the shock,to measure the lengths and what pound they are.
The body- I measured the height from the ground to wheel well lip. The left side is 1" higher than the right ? The body is flat on the frame under the doors but the left rear from the wheel well back is up off the frame say....1/2". All I can think of is the body is the left rear is warped going up ? Any other ideas ?
