There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.
Is 215/60/15 the right front Tire Size?

Recommended sizes will vary a bit by manufacturer.
One maker's size designation might be just a little bit different than another.
We just recently changed the tires on my wife's '17 RT-S. Installed Vredestein Q5s.
175/55 up front and 205/65 in the rear. Very happy with the choice.

VaCruiser if you have OEM wheels on the front they are 14 inch. the OEM tire is 165/65/14 for the 2011 Spyder RT

Worked great on our previous 2010 RT, and works great on our current 2016 RT.
I learn something every day here.
I was not aware that they had changed.
What year did they make the change?

From 14 inch front rims & tyres to 15 inch fronts?!
The 15's came with all the rest of the frame 'upgrades for the new 1330 motors' in 2013, only then the motors weren't ready in time, so the 2013 Spyders still hit the streets with the V-twins - so they got the best of both worlds! The frame & suspension upgrades; the bigger tires; and the peppier, more exciting, revvier motor!

Annnnnnnnnnnnnnnd great 14inch tires are hard to come by .... but you are in luck .... the best tire available today is the Vredestein Quatrac 5 ..... and comes in few 14inch sizes that fit your Spyder ..... Mike :2thumbs:

Good move. But, really you had no choice but to go with a non-OEM size. Nobody above seems to have mentioned it but there are almost no car tires the same size as the Kenda stock tire, so to go with a car tire you have to go non-stock size.

Just remember that while all that info is nice mrwog (& anyone else who may not realise!) it doesn't necessarily reflect the ACTUAL TIRE SIZES!! :lecturef_smilie:
It's only info based upon the NOMINAL Tire Size, ie the info printed on the sidewall and the sizes you entered into the table.... They are just a size chosen from a convenient 'Standardised Labelling Convention' agreement used across the International Tire Industry; they have little real relationship to the products that roll out of the tire factories, excpt that the size printed on the tire sidewalls is probably something CLOSE to that size...... But ACTUAL physical dimensions of most tires are often (usually! ) somewhat different, usually because the various manufacturers use different methods for choosing which Nominal size they are going to print on the sidewall. Some use the naked carcass size, before they even start to add/form the tread layers; some use the 'full depth tread' size, taken after the tire has been fully assembled; others seem to just pick something that looks like it might be 'pretty close'; and there's probably a whole 'nuther set of different methods used too, including 'just an educated guess', and often even for different spec tires made by the same manufacturer!! :gaah:
So while those 'Generic Size Comparison' tables are handy tools to use as a GENERAL Guide with APPROXIMATE size comparisons & approx information re speedo differences etc to help you start your tire choice, if you are that concerned about tire sizes (& sometimes you need to be!) then you really need to look at the ACTUAL Specifications of each tire you're considering and compare measurable things, like the Rolling Diameter, or the Revs per Mile - only if they happen to match EXACTLY for different tire brands/spec tires even tho they are labelled with the same Nominal size, that probably means that the manufacturer/s has been even lazier than usual/most & is only publishing the Nominal Data instead of the Actual measured Tire Size! :banghead:
Oh, and BTW, while the info you posted is certainly worth noting, with the above caveats
Sandee actually went ahead & ordered/bought tires a while back , and told us that at post #10 on the 8th of July. :thumbup:
