yes slowing print speed down helps.
As does printing more than one object at a time and also get a print area cooling fan if you don't already have one.

The smaller the object - and recently I've printed objects 3mm across and 2mm high. I do know what I'm talking about - the slower you print.

Think I went down as low as 10mm/s for the really small tyres and 20mm/s for the 'big' 6mm jobs.
