Calibre Bossnut Rear Tyre and size

I did a post months ago, and was told I could fit a 2.35 tyre on my Calibre Bossnut V2.
However looking at it and getting a ruler between the legs/supports i could get at least 2.8"
Just wanted to know any riders with the Bossnut and se what width they've fitted and what tyres they've gone for.
Is there a rule of thumb for tyre size on the rear i.,e. take 5mm off either size in case the wheel buckles or flattens to stop the tyre rubbing on the supports.

Ideally you want the rear tyre to be narrower than the front one.

I've been looking at the WTB Trail Boss or WTB Vigilante. Properly in 2.6 or 2.5.
Just wanted to know what people have put in their rear tyres on their Bossnuts.
I've got a 2.3" on the front.
A 2.4 is plenty big enough on the rear, on your bike in some brands that may be too big, Schwalbe tyres come up on the large side, my Magic Mary 2.35 at 62mm is as big as some 2.6 tyres, so as previous posts care must be taken.

#1 It is important to get the grip balanced front to rear. Ideally you need more grip on the front so that when cornering hard the rear lets go first.
#2 Having a faster rolling tyre on the rear helps to reduce drag on those long climbs that happen from time to time.
#3 What is the internal width of the rim on the rear wheel? For a 2.8" (71mm) tyre the internal rim width needs to be at least 30mm so that they tyre has a decent shape and doesn't look like a balloon. The shape has to be good otherwise the tread is not properly presented to the trail and you won't get the grip you are expecting. Also, the tyre beads will not be properly secured to the rim, which risks the tyre coming off the rim if you are pushing hard. See the link to the Schwalbe tyre knowledge sight, click on "which tyre fits which rim", look down the left to 70 and across to your rim width to see if it fits.

#4 You need room between the tyre and the frame. The frame flexes, the wheel flexes, the tyre carries mud and grit. The last thing you want is for the tyre and the frame to contact each other. Don't forget how close the wheel can come to the seat tube when the shock fully compresses, let the air out of the shock to check.
If you want to use a tyre that size on your bike, you would be far better fitting it to the front wheel, provided if will fit under the fork brace and reasons #3 and #4 above.
Ask yourself why you need more grip on the back? Is your rear wheel spinning out when climbing out of holes or up steep hills? If so, you can increase grip by changing the tyre for one of the same size but with a better tread pattern or one with a softer compound. But be careful about #1 and #2 above.
I weight 95kg.
I already have a 2.2 tyre on the rear, I'm finding this does not give me traction in the mud what so ever.
I have 2.3 WTB Vigilantes on the front and 2.2 WTB Bee Line on the rear.
I like the Bee Line and using it on the dry trails but it's terrible when going over leaves and mud. It just digs into the mud rather than cuts through it.
I won't get anything wider than a 2.5. I understand that the width stated can sometime be narrower depending on the stated recommended psi. So a 2.5 may be 2.5 @ 60psi but would measure around 2.3 @ 35 psi.
In the mud I pump it between 30-35 and 40 in the dry.
The Bee Line is a tyre for conditions we don't have at the moment, plus you're running too much air for mud, 27-29psi is probably enough for your weight, 2-3psi less in the front.
You need to change to a more suitable tyre for the winter.
You could put the Vigilante on the rear and get a new WTB Convict 2.5 for the front, or run Vigilantes front and rear.

I'm 14.5 stone (90kg) riding weight and I ride with 27.5 x 2.3" tyres 22psi F and 27.5 x 2.2" 24psi R. I have a Maxxis High Roller II 3C on the front and a Conti Trail King with bcc on the rear. The rear tyre was a Maxxis Crossmark II 2.25" on the rear, but although it was great in the summer, it had little grip in slippy conditions, even a little mud would have it spinning out.
I'm not going tubeless just yt, are these tough tyres less likely to get punctures?
Set the PSI as recommended and the ride feels better.
Bought the convicts from CRC, a pain to put on tubeless ready rims and bought some puncture resistant DR Sludge rim tape as I don't want to be having to try to get these tyres off on a trek.
