Daft tyre width question
Discussion
Just been on a ride today. I usualy do hard tack or tarmac so I have semi slicks on.
This ride was in a forrest up and down hill muddy with branches then on an old train track which was covered with stones. The tyres just couldnt cope (wheel spinning and sliding off branches and stones )and neither could I but thats a different story.
Anyway I dropped the bike off in my parenets garage and Ive come home straight on the net and ordered some tyres. I have no idea which didnt stop me.
anyway the tyres that are on now are 1.75 and I have ordered some Panaracer's which are 2.35 and I have just had a thought will they fit? I assumed that they will fit all mountain bikes is this true?
cheers
good point well made 
The bike is a Giant Terrago. the origonal tyres were 2.0 IIRC I took them off and gave them away when I first got the bike
The bike is the other side of town so cant go measureing gaps hence the question.
I quess I was hoping for a "Of course all mountain bikes can fit 2.35" answer but its not that simple by the sounds of it. hmmm quess I will just have to try them on and see.
Keep an eye out on the for sale section just in case

A quick google search and the 08 Terrago comes with 1.95's from the factory and a Suntour XCR 100mm fork.
My feelings would be that the 2.35 tyres maybe to wide for the frame. They may physically fit in the frame but would soon clog up in your current local muddy conditions. Or if you were to buckle the rear wheel whilst riding it would catch.
I couldn't find on the Suntour site any info of max tyre width - you'll need to check your fork manual on how to check that.
Personally, I like the XC Pro's. And I use the 1.8 in muddy conditions. Just get the black walled version.

URgh!Although I thouroughly enjoyed today going over the rough ground. If I keep it up I may upgrade the bike or get a new one at some point.

Sorry dude, I was not intending to mock. Suntour have a reputation for not lasting long when you try to use them hard. Be careful if you do anything too rough with them.
Doh! Just bought a GT Avalanche 1 Disc and its come with SR Suntour X100's.Arh well ill get saving.
Tyre pressures are a personal choice and dependant on many things.
The size of the tyre.
The type of tyre.
The type of riding beening done.
Ground conditions.
Whether the tyre runs a tubeless system or a tube.
The carcus construction of the tyre (two-ply, UST etc..).
The weight of the rider.
The skills of the rider (are they smooth or ham fisted?).
There is no definative answer. I run my 2.1 XC Pro's with Stan's No Tubes and at about 35psi - regardless of the ground conditions. I run my 1.8 XC Pro's with inner tubes and at about 45psi as this is roughly the 'softest' I can go without getting snake bites (although I will drop this pressure a bit once the new wheels are fitted and I go tubeless). Basically I run them soft enough so that the rim doesn't hit the ground.
Don't forget though that in the wet and the mud things are slippy so there will always be sliding around regardless of tyre pressure. It's good riding skills that help you in those situations.
Schwalbe's tyre download has a lot on tyre pressures - including an interesting (well to me) fact that at the same pressure a wide tyre will roll faster than a narrow tyre.
ETA: Having re-read your post you need to explain why you were struggling in the dry. I'd say (based on your limited post) it was rider issue not an equipment one.

My GF has a Giant bike (not sure of the exact model) and that has 2.35 Maxxiss tyres on it, they are very close to the frame, it is also hard work to ride the bike on road (which is all she uses it for, when she uses it) which I put down to the tyres.
Maxxis tyres can weigh in at well over 1.3Kg's each. Switch to something around 500-600grms and it will be so much nicer to ride you wouldn't believe its the same bike!_daveR said:

I stopped by this morning to measure before I cancelled the order and there is just over half an inch gap each side between the frame and the tyre edge on now. so 1.2inch in total gap and the tyres are .6 wider in total than current ones assuming they actually measure what they are supposed to.

It's wrong to assume that everyone who posts in this area is planning to attack extreme trails, and/or ride a thousand off road miles this year.
Whilst some kit may be compromised to a budget in some respects, there is nothing to say that kit at a lower level might be perfectly adequate for many kean riders needs - sure a £600 fox fork might be better in every way, but is in no way essential for many needs.
You CANNOT buy cycling enjoyment. The enjoyment comes from what your bike enables you to do, where it takes you, and what experiences you have out on your rides. Whether that takes place on a canal tow path on a £200 halfords entry level machine, or powering around whistler on a £3000 all mountain work of art.
How many people get blinkered by the NEED to own the latest and best kit, and forget why we enjoy cycling in the first place.
