Over done Tire question

I know the ZR rating on the big lady is a no no...but has anyone tried a 120/70/ZR17 for a front wheel application?

Regards,
Woody aka SoberBiker

Hey, Bud - how you be?? Long time no chat. You asked if anyone tried the 120/70/ZR17 tire for the front - I haven't, butt you want an opinion? Mine? Don't do it. Least not with Lori on the back. After model year '05, the radial ply tires aren't spec'd for the LT (they were for the ''99 to '04) due to a change in the steering geometry - now the call by folks in the bidness is for Bias ply. And not only that, butt the weight and speed rating for the recommended front tire fitment is 58V (not sure what the weight rating is for the tire you referenced).

Good luck, Woody; stay tuned for others to chime in. You take care, and best always.

Re: Over done Tire question

Its been a long time since I did any KLT tire research, so we're dusting off the memory banks here:
The change in steering geometry (started with the 05 model IIRC) was to improve slow speed handling. This change was at the expense of high speed stability (one reason why I like the pre-05 models).

With the 05 model owners started reporting more front end wobble, etc. (I think the newer bikes had greater sensitivity to tire balance and other tracking factors.)

And with that rake change, BMW's recommendation for tires switched from radial tires to exclusively bias ply. (do I still have this correct? Somebody correct me if I'm off base please.)

So load rating aside, IMO it makes sense to pay attention to both the bike's manufacturer's and the tire manufacturer's recommendations.

Yes ! I installed the Bridgestone BattleAx BT023F 120/70-ZR17 on my front about 1000 miles ago. It handles good , corners good, rides great. I'll probably go with an Avon or Michelin when the rear needs replacing. My bike is a '99. It was $110 with free shipping on Amazon & $20 install at a local shop. That was with the wheel off the bike.

As always Dick...thanks for the info.
I was thinking that the info you gave was what I thought might be the case. I was being lured by the low cost and being rather frugal these days, very tempted.
As far as the state of my condition...I be great! Just broke as always but aren't we all...LOL . I was on Social Security Disability for a minute but couldn't survive the financial, so...back to work. How you been? I was really hopin to get to the CCR this year but still recovering from the S.S. ordeal. One of these days the stars will line up and I'll make it back. I miss you guys!

Anyway, thanks all for the info and as usual I'm goin with the gut and spendin the money and getin the right tire. Damn it!

Regards,
Woody aka SoberBiker

Re: Over done Tire question

I put a Michelin Pilot on the front back in the middle of May. It's worn out now and I'm replacing it with a Metzeler this morning...............

Re: Over done Tire question

Woody, I agree with Seņor Dick on this one. Get the right tire, right ratings, and definitely bias if 2005+.

I posted yesterday on my Metzeler search and the pricing and July rebate I found.

I was going to put a Metz in the rear and Battlax up front, but with the rebate the Metz pair was a better buy. YMMV.
