Radials: Front-to-Rear and Rear-to-Front only, not side-to-side.

Bias-ply tires are/were rotated in an "X" pattern.

Well, there you have it; vrodders pay a 400% premium on tires for a bike that only has a 32% lean angle and is only marginally faster than a well built airhead. Don't get me wrong, your arguements are probably very fitting for a vmax, or the new diavel or maybe even the XR1200 *lol*

I ride with Fz1, dualsport, Sportbike, guys and have scraped every piece of the undercarrage, frame, rad, pegs, pipes brackets you name it, and do it on the daily (in riding season lol) to contrary belief a Vmax does not like corners and ride angles are a part of the cornering but not all. A skilled guy on a 500cc ninja could take down a 1litre bike with a newb on it. I ride my bike pretty hard and think that my safety is worth the extra bucks, my family would agree. I dont care what bike/car I buy the quality tires because there the only thing between you an the weeds. But too each there own, except when its needed and a car, bike with bald tires takes my family out because they were too cheap to replace them...

IMHO car tires are for cars and motorcycle tires are for motorcycles. If I was able to afford changing rear tires at 2000 miles I would. There is nothing better than a pair of new "shoes" on both ends of your ride. Even on my road king, I wouldn't even consider putting a car tire on the rear. The compounds are all wrong and with the square edges, even on a heavy touring bike, the sidewalls are entirely too stiff to allow for even marginal contact in a hard lean. My life and my wife's life aren't worth the cost savings. I will buy 10 to 1 motorcycle tires as opposed to a car tire. But thats why they make apples and oranges. If everybody liked apples there wouldn't be enough to go around. The car tire concept isn't only dangerous, but physics cannot possibly allow it to handle any better than a model T!! :soapbox:

Yes there are high performance car tires that are made for extreme cornering that will not survive for 10,000 miles. Very few people would ever need that on a car, almost everyone does need that on a bike.

yes, when i was heavy into racing I bought tires that would last MAYBE 10,000 miles on the rear of my SS - if i didn't do too many 1/4 miles races/burnouts. Some of the drag radials I would buy would only last maybe 3,000 miles.

those tires would be the more accurate comparison between a bike tire, and, it was not uncommon for me to spend $250+ for each 11" wide tire.

you mean to tell me you have never had the back end step out on your during a hard corner exit? because I do almost each time I ride (it's kinda fun). Also, are you telling me that you have never had a panic moment and grabbed a handful of front brake? because if you had, and you had a hard rubber front tire, you'd be on your ass sliding on the pavement.

though the v-rod can't benifit as much from sticky rubber as say the CBR in my garage, it certainly needs traction as much as any other bike in certain situations (hard acceleration/deceleration).

Oh ye who are intent on missing my point which is, ceteris paribus, motorcycle tires cost 4 times what a car tire costs because that is what we are willing to pay for them.

I get your point. But a lot of car and truck tires are quite expensive. I think the size of V-Rod tires is part of why they cost so much. The tires for my truck are outrageous too, because of their size more so than anything. If my wheels were smaller my tires would be much cheaper. There are dirt cheap bike tires out there, just not for our wheel sizes.

They are inarguably a bloody scam, one that most of us have bought into!

Try pricing a comparable high performance, Z rated car tire if you want a real scam, they also do not get lottso mileage. It's the "high performance" tag more so than the "bike" tag that fuels prices. Keep in mind also the amount of car and truck tires that are sold Vs. bikes.

Again, 32 degrees or 50 degrees - it does not hurt any less when my azz is dragging on the pavement, I want all the stick I can get. I've had the rear kick way out more than once with the stock Dunlop. Much tighter with the Cobra's and would pay more yet if it meant better all around. Lest not forget bad weather we all get stuck in on occasion as well.

Just a couple common sense items that jump out to me when comparing car tires and bike tires.

1: car tires are usually rotated between 4 different locations on the vehicle. You can sort of (not exactly) assume that a car tire should last about 3-4 times longer than a bike tire.

2: most car tires are not Z speed rated, most bike tires are.

3: most car tires are not made for sticky high speed cornering, some are and the ones that are are expensive and don't last very long. Most bike tires are made for this.

4. If (when the way I drive) you break traction on a car the ass end will slide around, you counter steer and make it look like you did it on purpose and go on about your business acting cool. On a bike you crash.

There's more but I'm bloviating. Bottom line, especially with a high dollar luxury bike, is that it's silly to attempt to save a couple hundred bucks a year for something that's not designed for the task. In litigious states you may even be opening yourself up to liability by using a car tire on a bike.

Not to mention there are obviously only 2 tires on a bike meaning if only one gives you're focked.

I have ZR rated tires on the Mustang.They will last probably 55,000 miles because the compound rating is well over 400.That's hard.
The high mph rated tires are made better to handle the force that does not exist,centrifugal.You can find any compound rating needed on a ZR tire,starting at 100.

i spy phone, kiwon wang If you must know, mobile phones can be the culprit for your company’s low productivity. What do I mean by that statement? As long as there is a mobile phone, your employees might be tempted to use it even on business hours. If that happens, they will be neglecting more of their pending jobs. Prevent that from occuring. That is why there is a need for you to have your own Spy US Phone. This is a one of a kind software that enables you to see other’s phone activities. If you feel that they are not maximizing their time to work because of their cell phones, then there is a need to change workers.

I say if an employee is stealing minutes from the employer,they should be shot in the forehead and killed.This would end cell phone abuse.There aint nothing worse than cell phone abuse as far as I am concerned! Cell phone abuse leads the employer to cut corners and install cheap car tires on their motorcycles.This puts the employer,and everyone around them in jeopardy of their lives.If your employer dies,you cannot get paid and there goes the economy again.
