It would be useless to find a tire for Sam the same as the one that he has been using since the build of the E-Z Hook. The tires were made some 15 years ago. The tire was only good for about 335 mph. The tire presents a problem above this speed as it chunks the rubber off. Sam was only getting two runs on the last few tires that he had after he got the mighty E-Z Hook running at speeds of over 340 mph. There are no 2.5"X17" or 3.0"X17" tires currently being made, or ever have been made, that have a speed rating needed to go 355+mph. This is not Sam's only tire problem.
The rear tire, which is a shaved Goodyear Frontrunner, is also at it's limit at 350 mph. Same problem. The tire chunks the rubber off. Both Sam and Denis use this tire. The fastest that this tire has ever gone to my knowledge is in the three wheeled Fueling car. The tires made it to 360 mph, and they started to self destruct.
During the 354 mph run made by Denis Manning, the rear, shaved Goodyear Frontrunner tire experienced chunking.
