Over 4,000 miles on my Bontrager T1s when I stopped counting miles. T1 ($20/ea) only available in 700c up to 25mm wide, the T2 ($25/ea)available up to 32mm. Mine are 27 x 1 1/4. Easy to mount, tread compound soft and grippy both dry and wet. No additional puncture protection but maybe a dozen flats on mine so far. They are good tires. 27 x 1 1/4 is 440g. Look them up.
