i'm in a similar situation
i had a 28c GP5KTL on the rear but the shop building th ebike thought the clearance from the tank was too tight so went down to a 25c. really disapointed as the rough roads around here mean the 28 is much nicer. i'm wondering if the 28c TR will fit as they are apparently a bit smaller than the TL.
i don't think the height of the tank will be the issue, the bottom position is fixed. it will be the flex in the seat tube and stays compressing the rear end down towards the wheel.
question for the specialized guys on here: what is the minimum clearance required?

Hi all
New here and relativity new to tri!
I have a 2021 Shiv Sworks Disc I bought second hand. I love it. Very fast. Very comfortable.
I am running the standard Roval 64 wheels but put 28” GP5000 TLs tires on. It seems the rear tire is catching the underside of the rear wing. The clearance around the wheel looks a bit wider in front than about the wheel. It really only happens when I’m going uphill over a bump at speed. I think when I am out of the saddle I can avoid it.
Now it’s a medium bike and I’m not that tall 5ft 4in but have a comfortable fit. The seat post had to be dropped a bit and had to cut the wing. The wing is now sitting just under the seat.
My question is can I run 28s in the Shiv? My reading would suggest yes but what is everyone’s experience?
If I can run 28s is my wing too tall? Should I get another half inch cut off? The LBS thinks my weight coming down onto the seat after a bump may be causing the tyre to engage with the wing. I’m not that heavy mind you (150lbs) but maybe heavy enough.
Photo attached for reference. I don’t think it’s uploading to the post. I have uploaded it here
