Hi guys,
Long time reader, first time poster. Hoping to get some wisdom off you guys if I can!
I'm currently in Senegal with my C5 on a round the world trip. So far we've done very well since starting out in England (I'm Australian...) but now it's time to change the tyres as the rear is heavily worn.
Trouble is that in Senegal finding the perfect on-spec tyres for replacements has been tricky. Specifically, the tyres I've been looking for are front: 90/90 18 and rear 110/80 18, as per the user manual. Sad to say that I don't think that these exist here in Dakar and I'm sure most of West Africa as well for that matter. There are, however, many 18" options to choose from, but, due to my inexperience, I'm unsure if these off-spec tyres will fit on the rims (and stay there!)
So, my questions are: how strictly should you abide by the manufacturers recommendations for tyre width and height and what are the consequences of going outside the box? What are the limits specifically for the C5 with 18" rims? Also, is there possibly a "go between" size that will fit on both the front and rear wheels? That would halve the number of spares I have to carry!
Thanks for any assistance you can offer and apologies if this question isn't new, I couldn't find a thread that discussed what the limits are for sizes, only which size was best!
Cheers,
Spook
