A 8J rim is a bit wide for a 235/45R18 winter tyre, because there's not much rim protection from kerbing damage. Imagine driving in deep snow where you can't see the kerb. Even a gentle nudge could see the exposed alloy rim easily scraped.

 

225/50R17 is a non-standard tyre size on the Octavia MK4, but very popular on the Octavia MK3 Scout and Yeti...and could be a good alternative to the standard 205/55R17 tyre size on the Octavia MK4.

 

The 10.1kg claimed weight of the below 17" alloy rim is considerably lighter than most 18" alloy rims. For comparison, the 18" COMET alloy rim on the Octavia MK4 is claimed to be a whopping 14.9kg...almost 50% heavier than the lightweight 17" rim.

Another option on a 7Jx17 ET45 alloy rim, is 235/50R17. There's not much availability of winter rated tyres in this size, but there's Hankook's latest H750 all-season tyre. Compared to 225/50R17, 235/50R17 would provide a little more rim protection from kerbing damage.

Thanks Carlston am just concerned about fitment but think I should be ok the tyres are already mounted to alloys and are in excellent condition
