Wheel / Tyre Weight Comparisons

[simon1966]

Hi All

I thought it may be worth starting some form of reference guide to the weights of various wheels and tyres fitted to our cars.

Not all will be interested in this but some will (like me), I wish this information was available when I was looking at changing my wheels and increasing diameter.

Anyway I have just changed my 18" AMG III's (cast aluminium) for 19" BBS LM's (forged aluminium) so had the opportunity to weigh them. The AMG's were weighed with winter tyres fitted as removed from my car. The BBS' were weighed before tyres fitted, I'm not sure how much difference compressed air would add or the lightweight BBS aluminium valves, but I'm thinking not a lot

AMG III's
18" x 8.5" ET30, fitted with 245/40/18 Conti Winter Contact 830P tyres (8.1mm tread)
TOTAL WEIGHT 56lb 14oz (inflated)

AMG III's
18" x 9.5" ET33, fitted with 265/35/18 Conti Winter Contact 830P tyres (7.1mm tread)
TOTAL WEIGHT 55lb 13oz (inflated)



BBS LM 154
19" x 8.5" ET32 - WEIGHT 25lb 6oz
Goodyear Eagle Asymmetric 2
245/35/19 (brand new) - WEIGHT 22lb 15oz
TOTAL WEIGHT 48lb 5oz (un-inflated)

BBS LM 155
19" x 9.5" ET32 - WEIGHT 25lb 1oz
Goodyear Eagle Asymmetric 2
275/30/19 (brand new) - WEIGHT 25lb 10oz
TOTAL WEIGHT 50lb 11oz (un-inflated)


Overall it looks like that even with increasing wheel size I have saved a fair bit of weight which what I was intending, or at least I didn't want to increase weight! In my situation this resulted in a total weight saving circa 27lb 6oz

Anything is lighter than an OEM AMG wheel! Haha.

Great idea, can you put all the weights into kg as well please.

Done

Thanks DM

They don't seem to list many MB or AMG variants though.

Also interestingly they list LM's in my sizes as somewhat lighter than mine. I guess the weight could change with different offsets as strangely my fronts are quite noticeably heavier than my rears due to the centres being heavier. I used 'Reuben Heaton' digital scales and my catfish weigh sling on a tripod, so my weights should be close to 100%, but maybe I should get my scales checked!?
