Biggest rear tire?

[Redwood839]

Hi Folks,

New here, hello!

Just wondering, my NC750X's rear tire is ending it's career soon and I'm looking for replacement. I'm looking to see if anyone has any experience fitting a bigger tire. I live in Costa Rica, and our roads are terrible, filled with pot holes and just outright bad roads all over the place. A bigger tire would give me a slightly better chance at surviving hitting holes and a little more cushion around our bad roads.

I saw someone say they put in a 150/60 tire which is a bit higher.

Anyone else with any similar experiences?

Thank you all.

I run 150/70 dirt oriented rear tires. Fit with no problem. Speedo is off. Going up 1 tooth on the rear sprocket will get the final drive ratio back close to stock so the speedo will be back close to stock.

I think a 300 tire would be really cool plus you probably wouldn't need to use the side stand anymore. (sorry just joking of course )

The 170/60-17 Shinko 705 is about the max size with a fender hugger. It also makes the speedo read 1 to 1.5 mph slow.

Not too much extra space all the way around:

This.

Thanks everyone for their response. I missed the official tire thread mentioning a couple of 150's.

What advantage does the Shinko 170/60-17 have over the Shinko 150/70-17? How much taller does it make the bike?

Ordering a set of Shikno's on Monday.

Thanks

Why go bigger ?

I went with the 150/70R17. My speedo always read low so this got it within 1 kph. The 150 fits like it was meant to be on the bike and I saw no difference in handling or performance. Its a very common tire used on many BMW bikes so pricing and availability are good.

Here is a tire size comparator chart from the original size to the 150/70-17 which many of us use:

Why go bigger ?

Usually it is just a compromise on what sizes are available for a given tire.
Unlike the cruiser market where they choose a huge tire for looks.

Why go bigger ?

not sure about the others, but around here the roads are terrible and potholes every where. This would add a little cushion to my ride, and slightly bigger stand against potholes.

Thanks everyone for the comparisons and opinions!

Redwood- it might be better to state your want as "taller" not "bigger"; as most people associate bigger actually meaning wider, not taller.

The width of a tire is obviously not going to do anything* regarding how well it can absorb bumps and potholes, and since you specifically are referring to wanting more cushion, that would equate to a taller sidewall, not a wider tread.


* barring an equal increase in aspect ratio (height to width) but usually the wider a tire gets, the lower the sidewall profile, again, unless we now further veer away from a minor tire change available to fit an NC700/750 X, and into the realm of "balloon" tires like you can find on things like Yamaha TW200 and ATV's.

Honestly I'm unsure as to whether or not a centimetre or so of higher sidewall is going to be all that helpful to combat potholes and rough roads, without introducing poor handling and possibly higher wear, therefor higher running costs too, etc.

If I were you, I would try to avoid as many craters in the road as possible, () while saving up for better suspension bits. It will cost more than a few sets of tires, but in the long run will still be there once the tires wear out.

The 170/60/17 is .78" wider and .24" shorter than the 150/70/17. I personally would pick the 150/70/17 because it is $17.00 cheaper than the 170/60/17. YMMV
Since the 120/70/17 has appeared. I plan on trying this setup, since I can buy two rear tires and one front for $40.00 less than my current set.

180/55/ZR17 Michelin PR4. No mods, great handling

Welcome to the forum. Please, could we all get a couple of long shots of that tire on the bike?

Hi Maxter, welcome to the forum! If you don't mind, where do you live in Vietnam? I was there once long ago and found it a beautiful country. Perhaps one day I will revisit.
