School me on the LS.

What's even funnier is I was stopped by an El Cajon based CHP coming off the 125 connector to SR94 heading west just before College Grove. Lol the officers told me they were pacing me for more than 5 miles but couldn't get close until I actually pulled over to adjust the timing. No ticket, just a tongue lashing. Whew!

I seriously doubt a CHiPer would given a warning for twice the limit (maybe you know someone). Both times I was 90ish I got cited; once for 80 the most recent for 70+. Both tickets in San Diego county. I also have 2 for 75 in a 65. The only speed warning I have ever (40 years of driving) received from a CHiPer was up north by Ferndale. 65 in a 55 was good enough for a warning but I sure couldn't have tint on my front windows. I have had quite a few warnings from "local" LEOs. I even got a no-front-plate in Nebraska (THANK YOU Mike Valentine!)!

The tire ratings I referred to were ratings from the factory. My '00 LS came with "H" rated and now has "W" rated tires; as does my wife's and my '06s.

Mine are w rated also. Some of them are y rated. Damn good tire.

Beginning in 1991, the speed symbol denoting a fixed maximum speed capability of new tires must be shown only in the speed rating portion of the tire's service description, such as 225/50R16 89S. The most common tire speed rating symbols, maximum speeds and typical applications are shown below:



L 75 mph 120 km/h Off-Road & Light Truck Tires

M 81 mph 130 km/h

N 87 mph 140km/h Temporary Spare Tires

P 93 mph 150 km/h

q 99 mph 160 km/h Studless & Studdable Winter Tires

R 106 mph 170 km/h H.D. Light Truck Tires

S 112 mph 180 km/h Family Sedans & Vans

T 118 mph 190 km/h Family Sedans & Vans

U 124 mph 200 km/h

H 130 mph 210 km/h Sport Sedans & Coupes

V 149 mph 240 km/h Sport Sedans, Coupes & Sports Cars

When Z-speed rated tires were first introduced, they were thought to reflect the highest tire speed rating that would ever be required, in excess of 240 km/h or 149 mph. While Z-speed rated tires are capable of speeds in excess of 149 mph, how far above 149 mph was not identified. That ultimately caused the automotive industry to add W- and Y-speed ratings to identify the tires that meet the needs of new vehicles that have extremely high top-speed capabilities.



W 168 mph 270 km/h Exotic Sports Cars

Y 186 mph 300 km/h Exotic Sports Cars

While a Z-speed rating still often appears in the tire size designation of these tires, such as 225/50ZR16 91W, the Z in the size signifies a maximum speed capability in excess of 149 mph, 240 km/h; the W in the service description indicates the tire's 168 mph, 270 km/h maximum speed.



225/50ZR16 in excess of 149 mph, 240 km/h
205/45ZR17 88W 168 mph, 270 km/h
285/35ZR19 99Y 186 mph, 300 km/h

Most recently, when the Y-speed rating indicated in a service description is enclosed in parentheses, such as 285/35ZR19 (99Y), the top speed of the tire has been tested in excess of 186 mph, 300 km/h indicated by the service description as shown below:

285/35ZR19 99Y 186 mph, 300 km/h


As vehicles have increased their top speeds into Autobahn-only ranges, the tire speed ratings have evolved to better identify the tires capability, allowing drivers to match the speed of their tires with the top speed of their vehicle.

Y stands for "Yeah Right"

Well, I guess I was cheating then. My mother was on the PD for 5years and then did a lateral to the Marshal's office. So, I had endless supply of PORAC stickers. Those were the days. I think they called it Professional Courtesy. The roads were extremely smooth back then so high speed was pretty safe. I wouldn't do that now though.

I am not one to go overboard with the ultra high speed ratings. I do like running the XL rated ones though and I would suggest anyone to consider those anytime.
