Should I go with 700x28 or 700x32 for my 2016 Tarmac?

Thank you so much, I took your advice and ordered GP5000s in 28mm. Rode on them for the first time in the morning, they were amazing. Handled the rough pavement exceptionally well, almost shocking. Didn't have to worry about every little break, crack, loose gravel on the road, and bump. Didn't throw me around on the descents either.

Gatorskins are fine on glass roads. But ride them on chipseal or worse and it's like dragging an anchor.
GP5000TL's in 28mm work like a charm for me.

Even the Continental Ultra Sports, the older version, were terrible riding compared to the Rubino Pro's or GP 5000's I have on my bikes now. Just something you won't know till you try. Perhaps only someone that rides frequently enough to be "in touch" with the road they are riding on will be able to tell. But I sure could tell a difference.

Would you mind measuring the gap between chainstays in the place where the tires is closest to the frame?
I wonder if 2011 Tarmac SL had narrower gap there than the 2016 Tarmac.....
I measured 31mm on my bike. and with that I think 28mm tire might be too big, even if the tire is exactly 28mm, not a bit more..
thanks

General rule of thumb is at least 3mm of clearance all around, so that would mean 25 or 26 measured when mounted. I'd be more concerned fitting a tire larger than 25mm through the brakes assuming they are also 2011 vintage.

Trying to see if
VITTORIA CORSA CONTROL G2.0 TUBULAR 700x28 would fit or I have to go with 25s (install on Zipp Firecrest 404)
Yes, there is also the brakes, I have TRPs and they have the flip lever that gives extra 1-2 mm clearance to install tires + adjustment contact screw..... wiling to use both for the occasional wheel install.... would be worth it..

Thanks appreciate the advice, even though I feel that is very conservative gap. Given how much space I have to play with, I would be happy with 2mm each side.... as normally you do not have to deal with wobble on road tires as much as MTB.

For tubulars, how much does the rim influence width? I would imagine that it's very, very little, if at all.

I just put on some other tires/ clinchers Michelin Pro course 700x25 which actually measure 26.4 mm on the clincher rim.... just for the optics to see how close to frame... this I think is OK... but getting really close....about 2.5mm on each side...
Elsewhere I have read the
VITTORIA CORSA CONTROL G2.0 TUBULAR 700x28 measured 27.3mm
Will sleep on it, ride some more the clinchers which are 26.4mm before making decision for either the 25mm or 28mm tubulars... thanks everyone for all the insight.

I have a 2016 Tarmac. 28mm seems extremely tight to me. They might clear, but any dirt or sand that adheres to the tire is going to scour the insides of the chainstays. I'd go with nicer 25mm rather than risk it.

This is like saying "With all due respect." If you didn't want our advice, you shouldn't have asked for it. Also, 3mm is not a conservative gap...the industry generally recommends 3-5 mm per contact point (seat tube, brake calipers, seat stays, chain stays, fork, fork crown, etc.), not total. Good luck running 1-1.5mm clearances.
