My head is spinning looking at tire posts for my XR100. I'm setting it up with XR80 Front wheel to do parking lot SM riding. So I'm looking for tires that are not that expensive, I'm having to fund mine and my sons MC habit so cost is key. I heard Cheng Shin trials tires are good?

Thanks for the help.

BT45's aren't the cheapest but they have some pretty impressive grip. They'll last quite a while longer than some cheaper tires so the cost up front is pretty irrelevant in the long run.

Pirelli Diablo Performance scooter tires are about $55 a pop, that's what I have on one of my XR100 16" wheel sets. 100 front, 110 rear... they are both front tires though. They stick very well too, no problems. I run 20psi in them on pavement, 10psi on flat track.

Yea the Pirelli Diablo Performance scooter tires are more in my price range. I understand the BT45's are very good tires and last long, but they are just out of my range right now for the pair.

I guess what Im looking for is that tire that works great but doesn't have the big name price tag on it. (like when the IRC M5B MX tire came out, no one knew about them and I was able to get them cheap, now they are as expensive as the others)

Anybody have a good set of BT45 take offs?

The Diablo was what we ran in Sept. with M1GP 24 hours Super Endurance at Willow springs. Worked great on my XR100

Father and son racing together = Awesome !!
Absolutely, its great watching his skill level improve. That's why cost is important for me because I plan on getting him a set of wheels and tires for road riding his 110. He likes riding dirt but really wants to roadrace. I would rather have the used stuff and get him the good stuff.

This year I ran Shinko 714's. They are scooter tires that stuck well and easily lasted all season for $60/set. front; 80/80-16 Rear;90/80-16

Someone else in our club ran Pirelli ML 75's. They also lasted all year and came in 5 bucks cheaper than the shinko's Front;2.50-16 rear;2.75-16

Both I would consider to be well worth the money and great tires!

Get both at Motorcycle-superstore.com

Now were talking! Great prices, seem a little thin though, any problems with that or did they do just fine?

OK, so i looked at a tire to rim application guide for the 16" tires which i listed below for future reference.

Hundo811, Looks like the Shinko tire sizes you listed look close enough, and the price is even better. If im correct the XR80 front is 1.4 and XR100 rear is 1.6.
I'm particular about having the right tire size/rim combo.

16" Tires Permitted Rim

225*16 1.20/1.40/1.60
60/100*16 1.20/1.40/1.60
250*16 1.40/1.60

70/100*16 1.40/1.60/1.85
300*16 1.60/1.85/2.15
80/100*16 1.60/1.85/2.15
325*16 1.85/2.15/2.50
350*16 1.85/2.15/2.50
90/100*16 1.85/2.15/2.50
100/90*16 2.15/2.50/2.75

460*16 2.15/2.50/2.75
100/100*16 2.15/2.50/2.75
110/80*16 2.15/2.50/2.75/3.00
110/90*16 2.15/2.50/2.75/3.00
120/80*16 2.50/2.75/3.00
120/90*16 2.50/2.75/3.00
510*16 2.50/2.75/3.00
130/80*16 2.50/2.75/3.00/3.50
130/90*16 2.50/2.75/3.00/3.50
140/80*16 2.75/3.00/3.50
140/90*16 2.75/3.00/3.50
150/80*16 3.00/3.50/4.00

Yeah, Looks Right

The tires are thin but my philosophy on the situation is this; The smaller the tire, the less they weigh. The narrower the tire, what better for a narrow rim!

The profile on both the shinko 714 and the pirelli ML75 are great. I feel the pirelli has the advantage over the shinko for 2 reasons; 1. Sidewall is taller making the profile more favorable. 2. Less and smaller tread grooves for more rubber on the road.

I never had a chance this year to test these tires in the rain so the shinkos could have an advantage in the rain with deeper and more pronounced grooves.

@Hundo811, Got the Pirellis mounted up today. Tires look good, i noticed that the sidewalls are pretty soft (I mounted them by hand, and skill of course:D)

How much pressure are you running on pavement?

Ill post a pic when i get the wheels mounted tomorrow evening.

I was running around 22psi in my BT45's of a similar size. Not sure how the soft side wall will play into things. The BT45 I couldn't get mounted by hand, very stiff.

I'd start around 22 and play with the pressures from there. Tire pressure is a very personal thing...

Well Pirelli ML75's mounted, ill start with 22psi and adjust from there as these are very different in size then the BT45's.

For those who are curious of how they look here are some pics.

22psi might be a little agressive. You will probably find the 16-19psi range better
