Shop just called and said the replacement in the 60 series tire will be a while. They can't find anything else in stock with the factory height. Is running a 70 series on the back a workable solution?

I'm kind of worried about it fouling up something, and obviously handling concerns as well. Finding the right size in the states is proving to be a difficult task. I'm also stuck with getting it from the same service shop, as I am getting a free replacement, though they have called other vendors in the area to no avail.

What brand and model tire?

Michelin Pilot Road 2's I think, whichever ones are the dual compound road biased tires they make. (i.e. not the 2CT's)

70 will give you 70% of 150 which will give you 120mm (4.7") of sidewall height vs 90mm (3.5") for the 60. So the difference will be about 1.2" . Maybe a 160/60 ?

Wow, thats a huge height difference. I don't think I want to go with something that drastic.

I have concerns about rubbing with the 160. I thought I saw that mentioned on the forum a few times.

try a supersport tyre, 180/55/17.

pirelli dragon supercorsa pro's are a fantastic tyre, i run this on track and it dosn't make any real difference to the handleing appart from it turns in a bit slower - but unless you are hangin your balls out on every corner you wont notice on the road

go a 160/60 rather than a 150/70.

Loads of guys use the 160's and are fine.
@ MO - cannot use a 180 and if you could it would ruin the handling.

i run a supercorsa pro which is awsome, thats a 160/60 with no problems at all. plus there the 1st tyre ive had confidance with to get my knee down and im sliding them everywere on these tyres (going through sliders quicker than tyres lol)

hope this helps

they work perfectly fine. pluss you will ALWAYS get a 180 as it is a super sport tyre.

dont tell me they cannot be used when i have already said that i run them.

P.S. my bike is a full race bike wich took 3rd at the northwest200 in 2005 ridden by alex donaldson who ran the same tyres.

MO, you're not running on OEM rims are you?
