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.

Well non-directional means just that ..... there will be no difference ..... i have that tire in 160/65-15 ... mine had a blue line on one side of the tread ... this was to show you you Exactly how to match the left & right side .... this means don't have one blue line on the inside and the other on the OUTSIDE ...or vice versa .... you can go to their web site for further info .... good luck ....

Could not find any mounting direction info on the Vredestein website. So you are saying mount them so looking from the front (or rear) they look exactly the same, not opposites?

Did you miss the part " blue line " ???? AND I corrected my post please re-read ...... Mike :thumbup:

Thanks Mike, that's what I thought. Looking forward to putting them to use. My fronts still look good at 12,000 miles but the rear has a 1 foot long section that is worn out. There rest of the rear tire could go several 1,000 miles. It should ride sooooooooooooooooooooooo much better.

And because these are AUTO tires myself and Peter recommend about 16-17 psi for the fronts ..... if you are really cranking it 18 psi ..... with auto tires and the lightweight of the spyder front end a small change in psi can really change performance ..... good luck ... Mike

It's going to be real interesting to see if this size fits on the front of a 2019 RT. Just laying the tire up beside the old one ....................uh. Don't remember seeing anyone running it on anything later than a 2018. Worst case, someone is going to get a great deal on two front tires for an older Spyder and I'll reorder for mine. Hopefully I can break away from work tomorrow and get them mounted.

Most folks on this forum who bought the 175 size , bought the 55 aspect ratio and they worked fine .... why did you get 65 aspect ratio ???? .... Mike :thumbup:

Well don't panic ... I have Altimax 175/65-15 tires on my RT ( with basic fenders ) I did have to use washers on the lugs to bring the tire out from the brackets a bit ... and it worked ..... the Altimax is the largest 175/65 -15 I have encountered .... so yours may well fit ..... but see if you can exchange them ... I have done this with TIRERACK and they didn't charge return shipping .... if that is where you bought them call them or whoever you did buy them from .... Mike :thumbup:
:agree: Another way of looking at 'which direction' to mount your asymetrical front tires - have a look at the tires as if they were already mounted on the Spyder and you are looking at them from in front of the Spyder.... and make sure the majority of the larger tread 'grooves' that channel water off a wet road and out to the sides of the tread as the tires roll are angled UP & OUT from the inside of both tires. It's not quite so visible on the Q5's, but the majority of the angled grooves of the pair of tires together should effectively make a (sort of) wide 'V' shape, with the point where the tires join at the ground being the lower/middle point of that 'V' and the outer/upper points of each side of the 'V' being on the outside of each tire. Admittedly, with the Q5's, it's more of a 'very flattened V with only slightly raised outside points', but I hope you get the drift!
Anyhow, if the tread grooves do this, then as the tire rolls forwards, the inner edge of each tire with those grooves on it will hit the ground first and as the tire contact patch is rolled forwards when the tire rolls forwards, any water or other dispersable debris on the road surface will be pumped OUT & AWAY from underneath the tire as well as away from being blasted in & underneath the Spyder - and this is VERY IMPORTANT for our Spyders (&Rykers too!) because if you pump any water etc IN & UNDER them instead, then sure, it'll tend to keep any spray bothering other road users down a bit, but guess what's coming along just behind where all that 'extra water' ends up?!? It's your REAR TIRE!! :yikes:
So by pumping all that water etc OUT & AWAY instead of IN & UNDER, you are avoiding creating a deeper layer of water over the road & therefore a greater traction risk for your rear tire & as any puddle/standing water etc will immediately try to run into the lower level area your front tires just created, you may even be improving the rear tire's chances of avoiding some high speed hydro-planing. :thumbup:

Thanks guys.
Mike, it was Tirerack.com. I will probably exchange if possible, if not then someone around here is going to get a great deal on a couple of tires.
Peter, If this pic displays correctly it would be of a left side tire, viewed from the front and I think it shows what you are talking about.

I don't know why mine has the " blue line " and yours didn't. I bought mine 8 mos. ago ..... but looking at the tread , there is a small difference in the tread bands ..... I would just make sure when they are mounted that the patterns are OPPOSITE from the other.... and if Vredestein lists them as " non-directional " .... they are .... PS, the Q-5 has one of the best " wet " road traction of any tire ( that fits spyders )...... Mike
Even better than the "blue line" and "groove direction" instructions, just read the sidewall.
One side of my tires says "INSIDE", so it is obviously mounted toward the bike.
The rear tire has the "INSIDE" mounted to the left, but it's non-directional, so it doesn't matter. :dontknow:

Actually, if you look at the siping & grooves, you may well find that ON YOUR SPYDER front end, it might be smarter to put the side labelled INSIDE facing OUT & AWAY from the Spyder!! :lecturef_smilie:
I must admit that I don't specifically know if this is the case for the Q5's, but most auto tires are designed to spray most of the water they force out from between the contact patch and the road surface IN & UNDER the auto (minimising road spray for other road users) which is exactly where you DO NOT WANT IT to go while ryding your Spyder on wet roads, or your traction may suffer! :shocked:
So as always, it does pay to check & carefully consider your specific application! :thumbup:

I went with the 175/55 fronts. So what direction does the rear go?
It doesn't really matter which way you put an asymetrical/non directional tire on the rear of your Spyder/Ryker, altho I have a tendency to put the side labelled INSIDE facing AWAY from the disc brake, purely because I like my brakes to work as well as they can, and I'd rather not spray any 'extra lubricant' onto the disc - altho any degradation a disc &/or pad wet with just WATER would make is going to be fairly minimal, but who's to say that whatever I might hafta drive thru is always going to be water?!? It could be contaminated water, with oil &/or other solvents/lubricants that don't work well with discs & pads, or maybe it could be a neat lubricant of some sort?!? :dontknow:
That sorta stuff has been known to happen, and by inspecting the tread pattern & mounting the tire to direct the 'clearing spray' AWAY from the disc (which usually means running the INSIDE label facing the mounted riders' left hand side) I like to think I'm just minimising the risk! :thumbup:
Of course, YMMV, as might your preference; but you did ask, and that's my preference & the reason for it.
