It's getting ridiculous. They can print whatever they want on the sides and on their website but the reality is that tires are getting skinner not wider than previous generations. My personal examples over the last 2yrs.
Probably the worst of the bunch.
- Road: The previous generation pro-1's that were 700x28 would blow up to typically 700x30'ish on my zipp 303 (25mm IW) rims. This is the pro 1's with the white "1" label. The new pro1's with the orange "1" blow up to about 700x28 on the same rim. So as advertised their but much less volume than the previous generation. Also the new gens' are about 60g over advertised weight where the previous gen's would typically come in under. I know nobody here cares about road, so i'll move on.
- MTB: Racing Ralphs 2.35.....ha!!! give me a break. mounted them on some 30mm Inner Width rims, and they didn't even blow up to 2.21. Beyond looking like CX tires on my mtb rims, they came in damn near 80g heavier than advertised. I couldn't return them because I already had sealant in them. I've learned my lesson to not mount with sealant now at first.
- MTB: They have this whole range "W.T." lines now which stands for "Wide Trail"... Wide Trail for who??
-- Rekon Race: Mounted to some 29x2.4 WT to 30mm IW rims, they blew up to 2.33 and came in about 64g over advertised weight.
-- Rekon: 29x2.4 mounted to 30mm IW rims...came out to 2.32 (granted this WT on this model do say meant for 35mm IW rims vs. 30mm like the rest of their WT stamps so bish too much)
-- Ikon: 29x2.35 mounted to 30mm IW rims... Came out to 2.23 which is not too far off, but still pretty narrow considering most of these are advertised wide
So specialized is a tough one. The previous generation were just outstanding in what was advertised and what you actually got. Every single tire I had of the previous generation would not only come in under weight, but would balloon well past their advertised width. For example,
- Previous Generation:
-- Fast Traks. advertised 29x2.3... on 30mm IW rims these would blow up to 2.37 on my rims and came within 5g of advertised weight. They were huge and great.
-- Ground Control. advertised 29x2.4 ... on 30mm IW these blew up to 2.48! They looked like fat bike tires.. They also came in under advertised weight. They were great
- current generation:
-- Fast Trak T-5 ..haha these are actually advertised at 5mm bigger than previous generation at advertised 2.35 now. On my 30mm IW rims they come out to a weak 2.27... wtf? Weight is as advertised within a few grams
-- Ground Control t-5. These werent' as bad as the fast traks, but still. advertised 29x2.35.. on my 30mm IW rims these actually get to advertised size at 2.36. Weight was dead on. Just noticible smaller than previous gen.
There's more out there, but these are just the most recent ones. Just seems like this is a new trend. They are all offering "wider" printed sizes compared to previous gens. Like you could never get a racing ralph in a 2.3 till this new gen, but it doesn't even matter when it doesn't get up to that size. Heck my old racing ralph 2.25 would blow up to 2.3 on 25mm IW rims. So there's that.
And yes all tires I blew up to max PSI, let sit for 48hrs, before riding them. I'd then do a couple rides on them and blow back up to max psi again just to see if they expanded. They don't typically for me. Maybe 1 or 2mm.
Buddy that manages a bike shop also noticed the same thing. All the new schwalbes road or mtb are really skinny and same with some maxxis. He did say the maxxis aspens blow up gigantic but the rest of the WT lines does not.
ok end rant:
