with my 15 mile each way commute being on my mind punctures will become
a very real issue for me to be able to deal with quickly and effectively
and also prevention of said nasties too - as mon-fri id be regularly
doing well over 100 miles per week (with the odd drive in when necessary
or when i end up at another branch office at the end of the day rather
than where my bike is)

currently, my cheap raleigh pioneer has 700/38c tyres - what would be a
good replacement considering the anti puncture theme and as i really
dont want punctures cost is less of an issue as getting to work on time
regularly is high on the agenda - also getting home too!

also, being on the very heavy side is sticking with 700/38c size tyres a
good idea as ive no idea what effect my weight / size of tyres / how
highly inflated they are, etc, etc has with regard to punctures, etc ...
apart from thinking a highly inflated tyre would be more prone to
punctures???

But they weigh a *lot* more than anything else! I get about one or two
a year with standard Marathons, which is acceptable IMHO.

with the weight im hoping to lose longer term (100 pounds approx) this
wouldnt be much of a problem? - after a couple of weeks im likely to
have lost half a stone or so which should easily make up for any
increased weight in the tyres, would it?

or does the increased weight of tyres make for a different kinda ride?

Heavier rims/tyres will change things a bit, but how much is really a
suck it and see job, I'd think.

also, those marathon plus ones were 26 x 1.75 - my current tyres are
700/38c so would they fit? whats the difference between these sizing
types?

26 is mountain bike size, 700c is the slightly larger diameter typically
seen on pure road machinery. So short answer is one won't fit on the
other. However, standard Marathons are available in loads of different
sizes (I use 16", 20" and 26" flavours myself, and I know there are 700c
ones too), so I wouldn't be surprised if there are more options on the M+.

does this just mean they get more skinny as the number reduces?

Yes, it's the width in mm.

Rule of Thumb is that the narrower the tyre the less the rolling
resistance tends to be (given appropriate pressures), though once you're
down in the lower 20s there are other tradeoffs so there's little point
even on serious racers to ride on real knife edges.
Wider tyres will generally soak up shocks better and ride much better
over rough surfaces (roads can be rough surfaces at times!), and they're
better at taking loads.

Laden touring typically uses 38 or 35, which is a good general size area
for a "do anything" bike that'll be carting a fair load. You'll go a
bit faster on 28 or narrower still, but only a bit, and the bike won't
take on as many different conditions so well.

MTBs for Serious Mud will use tyres over 2" wide, which are Just Great
in Serious Mud and are absolute purgatory on the road because it's so
much extra work to get them rolling.

Yeah, they are the best selling ATB slick where I work. I use kevlar
lined normal marathons (28C) and they havent punctured despite being
used on towpath, road and broken glass.

thanks ... have found the marathon plus at the same size 700x38 (i
assume the c doesnt mean anything?) - £21.99 each

I'd tend to go for the marathon because they are cheaper.
All sorts of modern tyres are a hell of a lot better in terms of punctures
than what we had as kids.
Actually if they are "snakebites" what you really need is a track pump
(cheap ones 12-20 quid).

Yep. With all due respect (and good luck to you), you could do with wide
tyres if you are 100lbs overweight.
You won't really get much of a difference in speed between the different
widths if you have decent modern tyres.
I say this as half of a "never quite been BMI30" tandem team.
