What size wheels and suspension set up do you have?
Do you feel (and I know this is debated about a lot!) that the numb steering is down to RFTs in the most part so do you know feel the steering is good?
Presumably you now have a spare? or carry one of those emergency inflation devices?
was the cost expensive, I had to replace a 19" 275 RFT tyre not long ago which came to £399 so a new set of tyres is presumbly not cheap even if non RFT
