• 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.

Tire pressures? (Again!)

Somewhere deep in the dark recesses of this feeble mind I recalled seeing where there was a posting warning not to exceed a certain front tire air pressure once the DPS unit was replaced... only now I can't remember where I saw it or what the pressures were! :shocked: Can anybody help me sort this out??
 
Bonneville Salt Flats requirements are 40 psi, the new (generation 2) DPS did very good. :thumbup:
 
I kept my front tires at 20 and the rear at 30 after the 2G DPS installation. The Spyder is solid as a rock. I am not an aggressive rider, but lower pressures make the tires feel like they are rolling in turns.
 
pop down warning sheet on your dash recomend 15 front 28 rear but I run 18 front and 30 rear. rear tire wears out fast enough as it is without higher pressure only got 12000 kms out of rear:gaah:
 
I should have added centre of rear wears very fast higher pressure would make it wear faster:yikes:
 
I got 20K out of my second OEM rear running 30 pounds. Got 28K out of the fronts with 20 pounds. I think the main reason for wear is the person's riding habit. We ride 2-up 99.9% of the time. Now have 10K on a rear Kumho, looks barely worn.
I did not change the pressures when I got the new 2G DPS.
 
I think another big factor in tire wear is improper inflation. I check mine 3 - 4 time a week (Spyder is my primary mode of transportation) and I can go several days with no change in pressure. Then out of the blue I can lose 5 lb in one tire. Go several more days without any changes, then lose air in another tire.

Of course it could just be the neighbors messing with me. :spyder:
 
18 front and 28 rear with stock tires. Mine have never lost more than 1LB of air while sitting all winter long.

Air pressure is most likely not going to make a difference in the wear on the rear tire. It balloons at speed causing the center to wear quicker. I tried more and less pressure to no avail..
 
I have been running 20 front and 25 rear. It is still wearing the center of the rear but the burnout mark is the same black all the way across! (old dragster trick, dark edges more air, dark center less air)
 
Based on spiderwolfs dragon pictures on the corners there is an awful lot of sidewalk flex on the kneads I would step it up to closer to twenty five in the front

I run twenty five all the way around but mine is a totally different beast
 
Max pressure for the rear on the sidewall is 30 psi. I have always run 28 and I can see the center of my tire caving in a bit. It looks like I'm running to low a pressure but 28 worked great on my last Spyder. I now have 30 psi and it is checked before eack ride. Back tire wear should be longer if 2 up riding, less slippage I would guess. Years ago we found that with Goldwings in our club.
 
I was at 20, 30, then 18, 28...vibration is MUCH greater with higher tire pressure, plus, I think the higher pressure leads to more tire wear issues (check around the site for old posts)...I'm at 16,26, and it's much more comfy to ride...the bike holds to the ground on twisties just fine...my dealer goes lower than that...
 
I started a year ago at 20-30 and have settled in at 18.5-19 and 27-28 and I check them every time out. 200 Lbs rider only.
