thanks ben but i need a whole wheel set at this point hence the new thread
When you say wheelset, do you mean hubs+spokes+rims+tyres? Or just new rims and tyres?
As far as complete wheelsets go, you won't get much for $250. You certainly won't be able to go into your LBS and pick out rims and hubs and get them to build it all up for you. You'll be pretty much limited to pre-built wheels from TBSM, CRC etc. And only cheap builds at that.
Even if all you're after is new rims and tyres, you'll have to factor in the cost of re-building the new rims onto the old hubs, which requires new spokes and nipples as well. I got a street/ DJ wheelset built up a few months back, I already had the rims and hubs and got my LBS to supply DT comp spokes and Pro-lock brass nipples. 36 spoke wheels, whole build cost me $250. Using cheaper spokes and nipples will bring the cost down, but labour alone was $80.
Depending on what you have currently, my advice would be to spend the extra money and get a pre-built wheelset. I recently bought a set of Mavic rims laced to Pro 2 hubs, with comp spokes and pro-lock nipples + rim tape, and it cost me less than $450, and so far I haven't needed to true it (though I will be taking them wheels into my LBS to be re-tightened, as it is highly recommended).
On the topic of tyres, I'll just repeat what I've said in a previous thread:
Tyres/ Tubes: Rotational weight makes a huge difference to how you bike handles. Whilst the hubs are far from lightweight, the stock rims are light enough to avoid having te replace the wheelset. Holy Rollers are overkill for the kind of bike you're looking for. Instead, I'd go for one of the following:
Kenda Combo: A Kenda NPJ Sig rear tyre, matched with a Small Block 8 front. The NPJ is nice and light, with minimal rolling resistance. The SB8 is quite a grippy 4X/ DJ tyre with a minimal weight penalty. From memory the weights are ~620g and ~680 respectively, as compared to a Holy Roller I think is almost a kilo.
Schwalbe Table Top: The TT is a very lightweight tyre with slightly less tread than a SB8 but a little more than an NPJ. The sidewalls are quite thin and the tyre profile is smaller than a Holy Roller, but it offers reasonable grip at ~580g.
There's a few other options around but these are the more popular ones. Whichever ones you go for, make sure you run lightweight tubes. DH tubes are overkill on the type of bike you want, and will make the bike feel heavy and sluggish, particularly in the air. Maxxis Welterweights are ~170g, and when inflated to the correct pressure should be resistant to pinch flats.
