Installing New Tires w/ Bad Rack & Pinion?

[pandrade]

i think it all depends on how bad your rack and pinion is. when i first got my supra the rack leaked all the fluid in about 5 minits. if this is your case then you could damage the ps pump which would add up to even more repairs.

changing tire sizes wont really do that much of a diffrence unless you go from like a suv tire and rim up front and facotry in rear( for about a year i ran 225 60 16 on the rear and 225 50 16 in front, the rear was way to tall but i dident notice a diffrence, except for traction). when it comes to driving on a bad rack it all depends on how bad it is. Mine would hold alighnment perfectly and steer just fine but i ran the risk of killing the ps pump, how bad is your's? does it leak, one of the ends wont fit the tie rod end; all back to the origonal question how bad and whats damadged about it
