And tonight's last question is from @daihard:
Q8. My new Marin DSX 1 comes with "WTB Riddler" tires. I have no experience with WTB tires, much less the Riddlers. Are they good all-season tires? I plan to keep them as long as I can, but if they're not suitable for year-round riding, I may switch sooner to those that are.
(What tires would you recommend for year-round riding?)
