The TIRE thread...

thanks. I shoulda guessed.

 

The GT501s are good tires IMHO... I've gone threw a few sets

 

hehe, woot said they're good, i'm sold. can get them for $200 shipped from ronayers.com

 

Just remember tires are about as personal as underwear. I'm sure there are other GT501 people here, if they could voice their opinions it would be good. You'll also find as many people who are happy on their tire of choice...

Actually - in one of the earlier posts someone refered to a post I made a long time ago... where I aluded to the tire debate - it can get as heated as an oil debate, politics or religion...

 

Can someone tell me if the 3.25/H19 4PR tire is the same as the 100/90 19
or the 110/90 19 or is it altogether a separate tire size.

 

I think, and could be wrong, that the first set of numbers is describing the rim in inches. 3.25" wide rim with a 19" diameter. I don't recognize 4PR.

The later is the size of the tire.

Check this out:

The CB750 (10 down or so) has the same front tire size and as notes says that a BT45 100/90V19 would fit properly. I don't know what that means as I don't know what 4PR means... sorry... trying to play detective.

Didn't find the XJ on the yamaha page:
http://mc.bridgestone.co.jp/en/products ... yamaha.pdf

 

Ya so that last post was dead wrong... it has nothing to do with rim size.

It's imperial for some reason... I'm still looking.

 

2nd page of Yamaha:

XJ750D 750 3.25H 19 4PR 120/90- 18 65H TL 1.85 2.15 — — #BT45V *BT45V L303 — #F:100/90V19

XJ750 has a front tire of 3.25H 19 4PR and in the notes that is listed as a 100/90v19 tire.

So from that I would say that I don't think a 110/90-19 is the same... it would be slightly taller and slightly wider... the rim it was designed for could be the same.

 

Thanks for all the info woot.
So I gather from that I should be looking for a 100/90V19 or the original
3.25/90H 19

I'm guessing the 4PR stands for 4 ply rating.

The H and V are the speed ratings I think.

 

oh - good call - that makes sense. That is almost certainly what that stands for.

Speed codes a la Wikipedia:
http://en.wikipedia.org/wiki/Tire_code

The V is up to about 150mph - more than enough for most of us H is only 130 mph... again fine for most people but surpassed by quite a few people... I used to have ZRs but never maxed them out

 

snick what kind of bike do you have? then we can telll you what size tire to go with. I have dunlop qualifiers on my X right now, but I just bought some new kenda cruizers that were recomended to me. The price was right at $110.00 for the pair and was told that they are an awesome modern tire for older "school" bikes

 

whoops, sorry bout that snick, guess I didnt read that you already mentioned what you had for a bike. I believe the size robert gave you is accurate

 

Tires...

Hey guys, I've alway received great advice from you so I'm going to throw this out there.

My 82 XJ1100 is almost due for some new tires. What do you guys recommend? Any particular tire that works best for this bike?

Thanks in advance!

Anyone try the new Dunlop elite III? I am seriously considering them to replace the spitfires on my XJ700N.

What are the Commanders like Samtidor?

 

I recently put a set of Metzler Lasertecs on my '82 750 SECA. The correct sizes and inflation amounts are listed on the sticker on the headstock. Sometimes it can be difficult to read due to cables/wires. I tend not to change tire sizes from the manufactures spec. Using a different size (usually bigger) will change the installed profile of the tire. Baasically the tire gets squeezed causing more of a "race" profile. This will lean/turn faster, but also be more unstable.

The lasertecs BTW are a fine tire from what I can tell so far. Good wet traction, and no problem dragging the pegs in the twisties. Confidence inspiring feel.

Firstly, the search function has helped me from starting a new topic and then being pointed to this one. Secondly, I'm in the market for some tires. I'm thinking of some whitewalls. Anyone have them on their maxim? I'd like to see a pic before I plunk down the $$$. Thanks.

 

A little side-line on this topic please,

How can one tell if the tire rubber is "hard" ?

Is there a method of testing or is it just a subjective call?

Thanks

 

I bought the new Metzler laserTec's; too. Love 'em in the corners and very nice highway performance. Quiet, no vibes; just right.

 

Sorry to bring this topic back from the dead, but anyone know where to get the best price on a set of Dunlop GT501 tires for front and rear? Oh, and a place that has them in stock and not on backorder would be nice.

1982 XJ550
Rear = 130/90 16
Front = 3.25 19

Thanks
