I was also planning to change the tyres. Drive almost 400kms now and found no reason to change. I'll keep using the same.
For accessories, i'll recommend you to buy them from the market where you can check the quality before making any payment.
Ive got airpress TXR good quality for 3500
Seatcovers for 8k
Steering cover-stitched for 600.
Floor mating 2000
5D matts for 3500
Boot matt for 1400
Fibre body kit is for 20k and plastic one us 38k.
Planning to get an Android screen as i didn't like ativ X display unit.
