So I have been running 18 psi front, 28 psi rear on my 2021 Spyder RT LTD, which seems to work well. I will probably still run those as it works for me.
However I wanted to know what the factory recommends as the manual says look under the front service cover on the right hand side. So I pulled the cover off, where the oil filler is. No label.
So it must be on the left hand side, silly me. So I put the right hand cover back and pull the left hand side off. No label.
Therefore where is it? By law it has to have one somewhere. Get the flashlight out and there is a label back under the seat where it is hard to read. Low and behold, there is a label describing the tire sizes and in the middle of the text is the tire pressures. 20 psi front, 28 psi rear.
So, if you follow the manual and can't find the label, it is back under the seat looking just like a generic warning label.
Just thought it might save some people some time looking for it like I was, and all the time I didn't have to take anything apart to find it. Phew.
