Stay away! I called this place for a price on one tire and they proceeded with the classic tire scam of needing 4 tires threatening severe damage to my vehicle because of the tread depth difference. The lady who took my call was obviously trained by a greasy tire salesman as this is a known scam. She then said I'd have to sign an agreement stating they were not liable and I said no problem. Once she finally got over her threatening sales pitch, she gave me a ridiculous price for one tire that was $150.00 more then the next highest tire dealer. If you measure 4 new tires of the same size in the circumference you will find that they are not the same and off by more then a millimeter. Further, roads are not straight and even on straight roads there is a crown. Only on a perfectly straight flat road when you drive perfectly straight and you have the same circumference tires you will see the wheel speed the same on all 4 corners of the vehicle. Wheel speed will also change depending on air pressure causing the circumference of the tires to increase or decrease. Then there are potholes and other road obstacles that will change tire wheel speed. All of this wheel speed is constantly changing while you drive, therefore if you buy a tire that is the same size (P235/75R15 for example) as the others but different tread heights you are likely not going to cause any damage to a vehicle unless the axle is a permanently locked differential (usually not street driven vehicles - only racing applications). Also, if you are worried about the slight variation in tire size due to tread you can shave the tire down or simply adjust tire pressures to accommodate the circumference change within reason (pay attention to the min / max tire pressure recommended by the OEM). In short stay away from this place or any place that tries to threaten you by needing 4 tires "or else". Even dealerships sometimes try this as the service writers have no real education other then what tire salespeople teach them or even sometimes the OEM service trainers will teach this tactic as they know it can result in money in the dealerships pockets. I worked for a tire outfit like Car-X years ago as well as a dealership both while going to school for automotive engineering. While working at these locations we were pressured to sell and often had tire salespeople giving this pitch to us in person or would have to attend tire sales training conference put on by the tire companies learning how to "teach the tire sale". Just be careful of who you trust (service people are sales people too!) and stay away from scammers like this sales lady at Car-X in Hudson.
